For the accesses to the configuration address space, the device select decoding is done externally and is signaled via this pin. This signal is asserted high during configuration read and write access. PCI Bus Command/Byte Enable During the address phase, these signals define the bus command or the type of the bus transaction that will take place. During the data phase, these pins indicate which byte lanes contain valid data. C/BE0# applies to bit7~0 and C/BE3# applies to bit 31~24. PCI Cycle Frame This signal is driven low by the master to indicate the beginning and duration of a bus transaction. It is deasserted when the transaction is in its final phase. PCI Initiator Ready This signal is driven low when the master is ready to complete the current data phase of the transaction. A data phase is completed on any clock both IRDY# and TRDY# are sampled asserted. PCI Target Ready This signal is driven low when the target is ready to complete the current data phase of the transaction. During a read, it indicates that the valid data is asserted. During write, it indicates that the target prepares to accept data. PCI Device Select DM6585 asserts the signal low when it recognizes its target address after FRAME# is asserted. PCI Stop This signal is asserted low by the target device to request the master device to stop the current transaction. PCI Parity Error DM6585 will assert this signal low to indicate a parity error on any incoming data. PCI System Error This signal is asserted low when an address parity is detected with PCICS bit31 enabled. The system error asserts two clock cycles after the address if an address parity error is detected. PCI Parity This signal indicates even parity across AD0~AD31 and C/BE0#~C/BE3# including the PAR pin. It is stable and valid one clock after the address phase. Reset: An active low signal used to reset the DM6588. +3.3V Auxiliary Power Supply Ring Signal Input for Auxiliary Power Auxiliary Ground

V.90 Integrated Data/ Fax/Voice/Speakerphone Modem Device Single Chip with Memory Built in DM6588 Functional Description
1. Operating Mode Selection The DM6588 MCU is include DM6588 external, DM6588 pci two types. 2. Micro-controller Program Memory The DM6588 supports two bank switch control pins to switch external program memory among four banks. The DM6588 can access a total of 256K of external program memory. Address mapping: bank0: 00000H - 0FFFFH bank1: 10000H - 1FFFFH bank2: 20000H - 2FFFFH bank3: 30000H - 3FFFFH For bank switching, three instructions must be included in software. Switch to bank1: CLR P1.3 SETB P1.7 JMP BANK 1 ADDRESS Switch to bank2: CLR P1.7 SETB P1.3 JMP BANK 2 ADDRESS Switch to bank3: CLR P1.7 CLR P1.3 JMP BANK 3 ADDRESS Return to bank 0: SETB P1.7 SETB P1.3 JMP BANK 0 ADDRESS For detailed information about the microcontroller, refer to the Programmer's Guide to 8032. Micro-controller Power Down Mode An instruction that sets the register PD (PCON.1) will cause the 80C32 to enter power down mode. There are two ways to wake up the 80C32 (1) Positive pulse signal occurring at the reset pin of the 80C32 (2) Negative pulse occurring at /RI (P1.0) of the 80C32 Enhanced Internal direct Memory There are two 128 byte banks of internal direct memory in the 80C32. The system uses the lower 128 bytes under normal conditions. Switching to the upper bank is achieved by loading register 8FH.1 (SFR of the 80C32) with 1. Switching to the lower bank can be achieved by loading the same register with 0. Reflash Program Memory By setting 8F.2H the system can switch program and data memory. If the system uses FLASH memory as program memory this function is used to reflash program code by downloading the program to data memory then switching them. Example: SETB LJMP 8FH.2 0000H

UART Clock (pci only) The internal clock of the virtual UART logic is fixed at 1.8432MHz. The clock is derived from the MSCLK signal from the DM6582 DSP, or an external 30Mhz crystal. The UART 1.8432MHz clock will be obtained by division. When the operating frequency of the DM6588 controller changes, the divider should be changed accordingly. This divider is specified by the Configuration Register which can be written by the DM6588 controller. The address mapping of the register is D400H: (DM6588 controller memory mapping) Bit 0: Always 0. Bit 6-1: define the clock divider range from 2 to 64 (even number). Bit 7: Not used. UART Baud Generator Divisor Latch Register: Address EC00H ( pci only ) Read only bit7 bit6 bit5 bit4 bit3 bit2 bit1 bit0 dat7 dat6 dat5 dat4 dat3 dat2 dat1 dat0 By reading this register, the micro-controller can monitor the value of the low byte divisor latch of the virtual UART baud generator (see DLL in next section) and determine the baud rate clock itself.

In order to provide minimum software overhead during data transfers, the virtual UART prioritizes interrupts into four levels as follows: Receiver Line Status (priority 1), Receiver Data Available (priority 2), Character Timeout Indication (priority 2, FIFO mode only), Transmitter Holding Register Empty (priority 3), and Modem Status (priority 4). The IIR register gives prioritized information regarding the status of interrupt conditions. When accessed, the IIR indicates the highest priority interrupt that is pending. Bit 0: This bit can be used in either a prioritized interrupt or polled environment to indicate whether an interrupt is pending. When this bit is a logic 0, an interrupt is pending, and the IIR contents may be used as a pointer to the appropriate interrupt service routine. When bit 0 is a logic 1, no interrupt is pending, and polling (if used) continues. Bit 1-2: These two bits of the IIR are used to identify the highest priority interrupt pending, as indicated in the table below. Bit 3: In character mode, this bit is 0. In FIFO mode, this bit is set, along with bit 2, when a timeout interrupt is pending. Bit 4-6: Not used Bit 7: FIFO always enabled.
This 8-bit register enables the four types of interrupts as described below. Each interrupt source can activate the INT output signal if enabled by this register. Resetting bits 0 through 3 will disable all UART interrupts. Bit 0: This bit enables the Received Data Available and timeout interrupts in the FIFO mode when set to logic 1. Bit 1: This bit enables the Transmitter Holding Register Empty Interrupt when set to logic 1. Bit 2: This bit enables the Receiver Line Status Interrupt when set to logic 1. Bit 3: This bit enables the MODEM Status Interrupt when set to logic 1. Bit 4-7: Not used Interrupt Identification Register (IIR): Address 2 Reset State 01h, Read only

This is a write only register at the same location as the IIR, which is a read only register. This register is used to enable the FIFOs, clear the FIFOs, set the RxFIFO trigger level, and select the type of DMA signal. Bit 0: FIFO Enable, This bit is always high Bit 1: Writing a 1 to FCR1 clears all bytes in the RxFIFO and resets the counter logic to 0. Bit 2: Writing a 1 to FCR2 clears all bytes in the TxFIFO and resets the counter logic to 0. Bit 3: Setting FCR3 to 1 will cause the RXRDY and TXRDY pins to change from mode 0 to mode 1 if FCR0 = 1. Bit 4-5: Reserved Bit 6-7: FCR6, FCR7 are used to set the trigger level for the RxFIFO interrupt. FCR6 0 0 1 FCR7 0 1 0 RxFIFO Trigger Level 01 04 08
Bit 0-1: WLS0-1 specifies the number of bits in each transmitted and received serial character. Bit 2: STB specifies the number of stop bits in each transmitted character. If bit 2 is a logic 0, one stop bit is generated in the transmitted data. If bit 2 is a logic 1 when a 5-bit word length is selected via bits 0 and 1, one and a half stops are generated. If bit 2 is a logic 1 when either a 6-, 7- or 8-bit word length is selected, two stop bits are generated. The Receiver checks the first Stop-bit only, regardless of the number of Stop bits selected. Bit 3: Logic 1 indicates that the PC has enabled parity generation and checking. Bit 4: Logic 1 indicates that the PC is requesting an even number of logic 1s (even parity generation) to be transmitted or checked. Logic 0 indicates that the PC is requesting odd parity generation and checking. Bit 5: When bits 3, 4 and 5 are logic 1, the parity bit is transmitted and checked by the receiver as logic 0. If bits 3 and 5 are 1 and bit 4 is logic 0, then the parity is transmitted and checked as logic 1. Bit 6: This is a Break Control bit. When it is set to logic 1, a break condition is indicated. Bit 7: The Divisor Latch Access bit must be set to logic 1 to access the Divisor Latches of the baud generator during a read or write operation. It must be set to logic 0 to access the Receiver Buffer, the Transmitter Holding Register, or the Interrupt Enable Register.

Bit 3: This bit is the Framing Error (FE) indicator. Bit 3 indicates that the received character did not have a valid stop bit. Bit 3 is set to a logic 1 whenever the stop bit following the last data bit or parity bit is detected as a zero bit (spacing level). The FE bit is reset whenever the CPU reads the contents of the Line Status Register. The FE error condition is associated with the particular character in the FIFO to which it applies. This error is revealed to the CPU when its associated character is at the top of the FIFO. Bit 4: This bit is a Break Interrupt (BI) indicator. Bit 4 is set to logic 1 whenever the received data input is held in the Spacing (logic 0) state for longer than a full word transmission time (that is, the total time of Start bit + data bits + Parity + Stop bits). The BI indicator is reset whenever the CPU reads the contents of the Line Status Register. The BI error condition is associated with the particular character in the FIFO to which it applies. This error is revealed to the CPU when its associated character is at the top of the FIFO. Bit 5: This bit is a Transmitter Holding Register Empty indicator. Bit 5 indicates that UART is ready to accept a new character for transmission. In addition, this bit causes the UART to issue an interrupt to the CPU when the Transmit Holding Register Empty Interrupt Enable is set high. The THRE bit is reset to logic 0 when the host CPU loads a character into the Transmit Holding register. In the FIFO mode, this bit is set when the TxFIFO is empty, and is cleared when at least 1 byte is written to the TxFIFO. Bit 6: This bit is the Transmitter Empty indicator. Bit 6 is set to a logic 1 whenever the Transmitter Holding Register (THR) is empty, and is reset to a logic 0 whenever the THR contains a character. In FIFO mode, this bit is set to 1 whenever the transmit FIFO is empty. Bit 7: In character mode, this bit is 0. In FIFO mode, this bit is set when there is at least one parity error, framing error, or break indication in the FIFO. If there are no subsequent errors in the FIFO, LSR7 is cleared when the CPU reads the LSR.

Bit 0: This bit asserts a Data Terminal Ready condition that is readable via port P1.1 of the microcontroller 80C32. When bit 0 is set to logic 1, the P1.1 is forced to logic 0. When bit 0 is reset to logic 0, the P1.1 is forced to logic 1. Bit 1: This bit asserts a Request To Send condition that is readable via port P3.4 of the micro-controller 80C32. When bit 1 is set to logic 1, the P3.4 is forced to logic 0. When bit 1 is reset to logic 0, the P3.4 is forced to logic 1. Line Status Register (LSR): Address 5 Reset State 60h, Read only bit7 bit6 bit5 bit4 bit3 RCV ETEMT THRE BI FE bit2 PE bit1 OE bit0 DR
This register provides status information to the host PC concerning character transfer. Bit 1-4 indicates error conditions that produce a Receiver Line Status interrupt whenever any of the corresponding conditions are detected. The Line Status Register is valid for read operations only. Bit 0: Set to logic 1 when a received character is available in the RxFIFO. This bit is reset to logic 0 when the RxFIFO is empty. Bit 1: An Overrun error will occur only after the RxFIFO is full and the next character has overwritten the unread FIFO data. This bit is reset upon reading the Line Status Register. Bit 2: A logic 1 indicates that a received character does not have the correct even or odd parity as selected by the Parity Select bit. This error is set when the corresponding character is at the top of the RxFIFO. It will remain set until the CPU reads the LSR.

Description PME_Support This five-bit field indicates the power states in which the function may assert PME#. A value of 0 for any bit indicates that the function is not capable of asserting thePME# signal while in that power state. bit27 PME# support D0 bit28 PME# support D1 bit29 PME# support D2 bit30 PME# support D3(hot) bit31 PME# support D3(cold) DM6588's bit31~27=11000 indicates PME# can be asserted from D3(hot) & D(cold). Reserved (DM6588 not supports D1, D2) A "1" indicates that the function requires a device specific initialization sequence following transition to the D0 uninitialized state. Auxiliary Power Source This bit is only meaningful if bit31 is a "1". This bit is "1" in DM6588 indicates that support for PME# in D3(cold) requires auxiliary power. PME# Clock "0" indicates that no PCI clock is required for the function to generate PME#. Version A value of 001 indicates that this function complies with the Revision 1.0 of the PCI Power Management Interface Specification. Next Item Pointer The offset into the function's PCI Configuration Space pointing to the location of next item in the function's capability list is "00h" Capability Identifier When "01h" indicates the linked list item as being the PCI Power Management Registers.

Description Reserved PME_Status This bit is set when the function would normally assert the PME# signal independent of the state of the PME_En bit. Writing a "1" to this bit will clear it. This bit defaults to "0" if the function does not support PME# generation from D3(cold). If the function supports PME# from D3(cold) then this bit is sticky and must be explicitly cleared by the operating system each time the operating system is initially loaded. Reserved. It means that the DM6588 does not support reporting power consumption. PME_En Write "1" to enables the function to assert PME#, write "0" to disable PME# assertion. This bit defaults to "0" if the function does not support PME# generation from D3(cold). If the function supports PME# from D3(cold) then this bit is sticky and must be explicitly cleared by the operating system each time the operating system is initially loaded. Reserved Power State. This two bits field is both used to determine the current power state of a function and to set the function into a new power state. The definitionis given below. 00 : D0 11 : D3(hot)

PCI function power management state The DM6588 supports PCI function power states D0, D3(hot), D3(cold). Additional PCI signal PME# to pin A19 of the standard PCI connector.
Before enter D3(cold) state, host must : 1. Write 1 into PME_Status bit to clear previous PME status 2. Write 1 into PME_En bit to enable PME function.
PME Context PME (power Management Event) context is defined as the functional state information and logic required to generate power management events(PMEs), report PME status, and enable PMEs. For MODEM, PME context consists of PME_En bit, PME_Status bit , Ring Detect ,and Ring to PME circuit.
3. Write 3 into Power_state 4. Power off PCI bus. When Ring comes, Ring to PME# circuit check if PME_EN=1 and Power_staus <>0. If yes, assert PME# and set PME_Status=1. When host detect PME# asserted, it will power up PCI bus and assert RST# to initialize pci modem. At the same time, it write 1 into PME_En bit or PME_Status bit to stop PME#.
PCI MODEM Power Management Operation During a true power-on situation (no auxiliary and normal power), PME_En = 0 to avoid to assert PME#. When assert RST#, the pci configuration space is set to default value except PME context which must preserve. DM6588 can not assert PME# from D0. But can Assert PME# from D3(hot) and D3(cold). Hence the Ring to PME# circuit must check the power state. If ring comes at D0 power state, it can not assert PME#. Before enter D3(hot) state, host must : 5. Write 1 into PME_Status bit to clear previous PME status 6. Write 1 into PME_En bit to enable PME function. 7. Write 3 into Power_state When Ring come, Ring to PME# circuit check if PME_EN=1 and Power_staus <>0. If yes, assert PME# and set PME_Status=1. When host detect PME# asserted, it will re-initialize Software will enable its use by setting the PME_En bit in the PMCSR. It must continue to assert PME# until software either clears the PME_En bit or clears the PME_Status bit. pci modem and set Power_State=0 to return D0 state. At the same time, it write 1 into PME_En bit or PME_Status bit to stop PME#.

V.90 Integrated Data/ Fax/Voice/Speakerphone Modem Device Single Chip with Memory Built in Chip 2 : DM6580 Analog Front End Description DM6580
The DM6580 is a single chip Analog Front End (AFE) designed to be implemented in voice grade modems for data rates up to 56000bps. The DM6580 is an essential part the complete modem device set. The AFE converts the analog signal into digital form and transfers the digital data to the DSP through the serial port. All the clock information needed in a modem device is also generated in the DM6580. Differential analog outputs are provided to achieve the maximum output signal level. An audio monitor with programmable volume levels is built in to monitor the on-line signal. Inside the device, a 16-bit ADC and a 16-bit DAC with over-sampling and noise-shaping techniques is implemented to maximize performance. received without amplitude distortion and with minimum group delay. In order to support multi-mode modem standards, such as V.90, V.34+, V.32bis, V.32, V.22bis, V.22, V.23, V.21, Bell 212A, Bell 103, V.17, V.29, V.27ter, programmable baud and data rate clock generators are provided. For asymmetric channel usage, the transmit and receive clock generators are independent. In order to enhance echo-cancellation, the receive clock is synchronized with the transmit clock and the best receive timing sample is reconstructed by a reconstruction filter. The Transmit Digital Phase Lock Loop (DPLL) is selftuning to provide a master, slave or free-running mode for the data terminal interface. A receive DPLL that is step programmable by the host DSP is implemented to get the best samples for the relevant signal processing.
The DM6580 offers wide-band transmit and receive filters so that the voice band signal is transmitted or

DM6580 Functional Description
In this chip, we could roughly divide it into two major parts: digital portion and analog portion. The functional blocks are described separately in this section. The analog circuits include a sigma-delta modulator/demodulator, decimation/interpolation filters, a speaker driver, low-pass filter and certain logic circuits. The digital circuits is composed of Tx/Rx clock generator/PLL, serial port, serial/parallel conversions and control registers. All the clock information the analog circuits need should be provided by the digital clock system since the best sampling instant of A/D and D/A depends on the received signal and transmit signals. The data format of A/D and D/A is 2's complement.
Preliminary Version: DM562P-DS-P02 February 28, 2001
The master clock (FQ) is obtained from an external signal connected to CLKIN. The different transmit and receive clocks are obtained by master clock frequency division in several programmable counters. The Tx and Rx clocks can be synchronized on external signals by performing the phase shifts in the frequency division process. Two independent digital phase locked loops are implemented using this principle, one for transmit clock system, the other, receive clock. The tracking of the transmit clock is automatically done by the transmit DPLL circuit. The receive DPLL circuit is controlled by the host processor and it is actually an adjustable phase shifter.
