This interface provides much less Data transfer on the LPC bus is serialized over a 4 bit The general characteristics of the interface implemented in F81218 are listed as 5.2 UART -11- August, 2007 V0.33P F81218 A Universal Asynchronous Receiver/Transmitter (UART) is used to implement serial communication. The F81218 incorporates six fully function UART compatible with NS16550D. The UART ports perform serial to parallel conversion on receiving characters and parallel to serial conversion on transmitting characters. The controllable characteristics of the data transmission are baud rate, number of information bits per character, type of parity checking, number of stop bits and breaking the transmission. The serial format is a start bit, followed by The five to eight data bits, a parity bit(if programmable), and one, one and half, or two stop bits. UART also includes completed modem control capability and interrupt system that may be software trailed to the computing time required to handle the communication link. also has a FIFO mode to reduce the number of interrupts presented to the CPU. there is 16-byte FIFO for both receive and transmit mode. 5.2.1 UART Port Register The UART In the UART, 5.2.1.1 Receiver Buffer Register - Base + 0 Power-on default [7:0] = 0x00h.

IrDA SIR specifies asynchronous serial communication at baud rate up to 115.2Kbps. Each byte is sent serial LSB first beginning with a zero value start bit. A zero is signaled by sending a single infrared pulse at the beginning of the serial bit time. A one is signaled by the absence of an infrared pulse during the -16- August, 2007 V0.33P F81218 bit time. IRTX acts as a transmit pin and IRRX acts as a receiving one. As for detail description, please refer to register description. 5.4 Watch Dog Timer Function Watch dog timer is provided for system controlling. If time-out can trigger one signal to low level, the signal default is tri-state (need external pull up resister). The time interval has three ways: One is the hardware power on setting to enable, timer set to 10 second (24MHz). If 48MHz clock input, the timer is set to 5 second. Two is programmed by registers. The other is set the base address into registers, and use the base address the control it.

This allows a signal line to be used to report the The clock source is the PCI clock. The legacy ISA interrupt requests. Because more than one device may need to share the signal serial IRQ signal line, an open drain signal scheme is used. serial interrupt is transferred on the SERIRQ signal, one cycle consisting of three frames types: a start frame, several IRQ/Data frame, and one Stop frame. 5.5.1 Start Frame There are two modes of operation for the SERIRQ Start frame: Quiet mode and Continuous mode. In the Quiet mode, the peripheral drives the SERIRQ signal active low for one clock, and This brings all the states machines of the peripherals from idle to active states. This makes the total number of then tri-states it. The host controller will then take over driving SERIRQ signal low in the next clock and will continue driving the SERIRQ low for programmable 3 to 7 clock periods. for one clock and then tri-states it. low for 4 to 8 clock periods. clocks low for 4 to 8 clock periods. After these clocks, the host controller will drive the SERIRQ high In the Continuous mode, only the host controller initiates the The host controller drives the SERIRQ signal START frame to update IRQ/Data line information. for the host controller to initiate the first Start frame. 5.5.2 IRQ/Data Frame Once the start frame has been initiated, all the peripherals must start counting frames based on the rising edge of the start pulse. low if the corresponding IRQ is active. left tri-stated. Each IRQ/Data Frame is three clocks: Sample phase, If the corresponding IRQ is inactive, then SERIRQ must be During Recovery phase, and Turn-around phase. During the Sample phase, the peripheral drives SERIRQ During the Recovery phase, the peripheral device drives the SERIRQ high. Upon a reset, the SERIRQ signal is defaulted to the Continuous mode the Turn-around phase, the peripheral device left the SERIRQ tri-stated. The IRQ/Data Frame has a number of specific order , as shown in Table 5-1. The F81218 is only support IRQ3, IRQ4, IRQ5, IRQ9, IRQ10, and IRQ11.

Only the host controller can initiate the Stop frame by driving SERIRQ low for 2 or 3 If the Stop Frame is low for 2 clocks, the next SERIRQ cycle's Sample mode is the Quiet If the Stop Frame is low for 3 clocks, the next SERIRQ cycle's Sample mode is the Continuous mode. -19- August, 2007 V0.33P F81218 6. Register Description Registers are programmed by port 0x4E and 0x4F. 0x4E is the index port and 0x4F is the data port . To enable configuration registers programming, entry key must output twice to index port continuously. The entry key is decided by power on setting pins RTS2#/PS_CONF_KEY1 and RTS3#/PS_CONF_KEY0 as following: RTS2#/PS_CONF_KEY1 0 0 1 1 RTS3#/PS_CONF_KEY0 0 1 0 1 Entry key 0x77 ( default ) 0xA0 0x87 0x67 To exit configuration registers programming, output 0xAA to index port.
