4-Bit Microcontroller with Built-in RC Oscillation Type A/D Converter and LCD Driver
GENERAL DESCRIPTION
The MSM64164C is a low power 4-bit microcontroller that employs Oki's original CPU core nX4/20. The MSM64164C is best suitable for applications such as low power, high precision thermometers and hygrometers. The MSM64P164 is a one-time-programmable ROM-version product having one-time PROM (OTP) as internal program memory. The MSM64P164 is used to evaluate the software development. The MSM64P164 differs from the MSM64164C in the polarity of the power supply.

Program Memory Map Address 000H is the instruction execution start address by the system reset. The CZP area from address 010H to address 01FH is the start address for the CZP subroutine of 1-byte call instruction. The start address of interrupt subroutine is assigned to the interrupt address from address 020H to 03DH. The user area has 4064 bytes of address 000H to address 0FDF. No program can be stored in the test program area.

Data Memory The data memory area consists of 8 banks and each bank has 256 nibbles (256 4 bits). The data RAM is assigned to BANK 7 and peripheral ports are assigned to BANK 0.

Data Memory Map Half the data RAM area (128 nibbles) is shared by the stack area. The stack is a memory starting from address 7FFH toward the low-order addresses where 4 nibbles are used by Subroutine Call Instruction and 8 nibbles are used by an interrupt. The addresses 080H to 0FFH of BANK 0 are not assigned as the data memory, so access to these addresses has no effect. Moreover, it is impossible to access BANK 1 to BANK 6.

FUNCTIONAL DESCRIPTION
* A/D converter (ADC) The MSM64164C has a built-in 2-channel RC oscillation type A/D converter. The A/D converter is composed of a 2-channel oscillation circuit, Counter A (CNTA0-4, a 4.8-digit decade counter), Counter B (CNTB0-3, a 14-bit binary counter), and A/D Converter Control Registers 0 and 1 (ADCON0, ADCON1). By counting oscillation frequencies that vary depending on a resistor or capacitor connected to the RC oscillation circuit, the A/D converter converts resistance values or capacitance values to corresponding digital values. By using a thermistor or humidity sensor as a resistance, a thermometer or a hygrometer can be constructed. By applying a separate sensor to each channel of the 2-channel RC oscillation circuit, it is also possible to extend measure ranges or measure at two places. * Serial port (SIOP) The MSM64164C has an 8-bit synchronous serial port. Receive/transmit operation of the serial port is performed simultaneously and the serial transfer clock can select either internal or external mode. Direction of transfer data can be big endian or little endian. Each pin of the serial port is assigned as secondary functions of P3.3 and P4.0 to P4.2. Setting each bit of SIN, SOUT, SPR and SCLK of P33CON and P40CON to P42CON to "1" makes each pin valid. * LCD driver (LCD) The MSM64164C has a built-in LCD driver for 34 outputs. The LCD driver consists of 31 4-bit display registers (DSPR0-30), the Display Control Register (DSPCON), a 34-output LCD driver circuit, and a bias generation circuit (BIAS). There are three types of driving methods: 1/4 duty, 1/3 duty and 1/2 duty. Software selects the duty mode. A mask option can select either a common driver or a segment driver for each LCD driver pin. A mask option can also specify assignment of each bit of the display register to each segment. All the display registers must be selected by a mask option. L26 to L33 of the LCD driver can be configured to be output ports by a mask option. The relationship between the duty, the bias method, and the maximum segment number follows: 1/4 duty 1/3 bias method ------- 120 segments 1/3 duty 1/3 bias method ------- 93 segments 1/2 duty 1/2 bias method ------- 64 segments * Buzzer driver (BD) The MSM64164C has a built-in buzzer driver with 15 buzzer output frequencies and 4 buzzer output modes. Each buzzer output is selected by the Buzzer Control Register (BDCON) and the Buzzer Frequency Control Register (BFCON). * Capture circuit (CAPR) The MSM64164C captures 32 Hz to 256 Hz output of the time base counter at the falling of Port 0.0 or 0.1 (P0.0 or P0.1) to "L" level when the pull-up resistor input is chosen, or at the rising to "H" level when the pull-down resistor input is chosen. The capture circuit is composed of the Capture Control Register (CAPCON) and the Capture Registers (CAPR0, CAPR1) that fetch output from the time base counter.

* Watchdog timer (WDT) The MSM64164C has a built-in watchdog timer to detect CPU malfunction. The watchdog timer is composed of a 6-bit watchdog timer counter (WDTC) to count a 16 Hz output and a watchdog timer control register (WDTCON) to reset WDTC. * Clock generation circuit (2CLK) The clock generation circuit (2CLK) in the MSM64164C contains a 32.768 kHz crystal oscillation circuit, a 400 kHz RC oscillation circuit, and a clock control port. This circuit generates the system clock (CLK) and the time base clock (32.768 kHz). The system clock drives the CPU while the time base clock drives the time base counter and the buzzer driver. Via the contents of the frequency Control Register (FCON), the system clock can be switched between 32.768 kHz (the output of the crystal oscillation circuit) and 400 kHz (the output of the RC oscillation circuit). Note: The oscillation frequency of the RC oscillation circuit varies depending on the value of an external resistor (ROS), operating power supply voltage (VDD), and ambient temperatures (Ta). * Time base counter (TBC) The MSM64164C has a built-in time base counter (TBC) that generates clocks to be supplied to internal peripheral circuits. The time base counter is composed of 15 binary counters and a 1/ 10 frequency dividing circuit. The count clock of the time base is driven by the oscillation clock (32.768 kHz) of the crystal oscillation circuit. The output of the time base counter is used for the buzzer driver, the system reset circuit, the watchdog timer, the time base interrupt, the sampling clocks of each port, and the capture circuit. * I/O port Input-output ports (P2, P3, P4) (12 bits) : Pull-up (pull-down) resistor input or highimpedance input, CMOS output or NMOS open drain output: these can be specified for each bit; external 0 interrupt Input port (P0) (4 bits) : Pull-up (pull-down) resistor input or highimpedance input; external 1 interrupt Output port (P1) (4 bits) : CMOS output or NMOS open drain output * Interrupt (INTC) The MSM64164C has ten interrupt sources (10 vector addresses), of which two are external interrupts from ports and eight are internal interrupts. Of the ten interrupt sources, only the watchdog interrupt cannot be disabled (non-maskable interrupt). The other nine interrupts are controlled by the master interrupt enable flag (MI) and the interrupt enable registers (IE0, IE1 and IE2). When an interrupt condition is met, the CPU branches to a vector address corresponding to the interrupt source.
