9 / 102 page  GMS81C5108 6 JUNE 2001 Ver 1.0 5. PIN FUNCTION VDD: Supply voltage. VSS: Circuit ground. AVDD: Supply voltage to the ladder resistor of ADC cir- cuit. To enhance the resolution of analog to digital convert- er, use independent power source as well as possible, other than digital power source. AVSS: ADC circuit ground RESET: Reset the MCU. WDTOUT: Output for detection of a program malfunc- tion. If the user wants to use this pin, connect it to the RE- SET pin. REMOUT: Signal output of an infrared remote controller. XIN: Input to the inverting oscillator amplifier and input to the internal main clock operating circuit. XOUT: Output from the inverting oscillator amplifier. SXIN: Input to the internal sub system clock operating cir- cuit. SXOUT: Output from the inverting subsystem oscillator amplifier. SEG0~SEG36: Segment signal output pins for the LCD display. See "19. LCD DRIVER" on page 71 for details. COM0~COM3: Common signal output pins for the LCD display. See "19. LCD DRIVER" on page 71 for details. SEG34~SEG36 and COM1~COM3 are selected by LCDD of the LCR register. R00~R07: R0 is an 8-bit CMOS bidirectional I/O port. R0 pins 1 or 0 written to the Port Direction Register can be used as outputs or inputs. Also, pull-up resistors and open- drain outputs can be assigned by software. In addition, R0 serves the functions of the various follow- ing special features. R10~R17: R1 is an 8-bit CMOS bidirectional I/O port. R1 pins 1 or 0 written to the Port Direction Register can be used as outputs or inputs or schmitt trigger inputs. Also, pull- up resistors and open-drain outputs can be assigned by software. In addition, R1 serves the functions of the various follow- ing special features. R20~R23: R2 is a 4-bit CMOS bidirectional I/O port. Each pins 1 or 0 written to the Port Direction Register can be used as outputs or inputs. Also, pull-up resistors and open- drain outputs can be assigned by software. In addition, R2 serves the functions of the various follow- ing special features . R30~R33: R3 is a 4-bit CMOS bidirectional I/O port. Each pins 1 or 0 written to the Port Direction Register can be used as outputs or inputs. Also, pull-up resistors and open- drain outputs can be assigned by software. In addition, R3 serves the functions of the various follow- ing special features . VCL0~VCL2: Power supply pins for the LCD driver. The voltage on each pin is VCL2 > VCL1> VCL0. See "19. LCD DRIVER" on page 71 for details. VLCDC: LCD drive voltage booster reference. CAPH, CAPL: LCD drive voltage booster capacitor. VREG: Output of the voltage regular for the sub clock os- cillation circuit. Connect external 0.1uF capacitor to this pin when using the sub system clock. Port pin Alternate function R00 R01 R02 R03 R04 R05 R06 R07 INT0 (External interrupt 0) INT1 (External interrupt 1) INT2 (External interrupt 2) Event counter input Buzzer Output SCK (SPI CLK Input/Output) SO (SPI Serial Data Output) SI (SPI Serial Data Input) Port pin Alternate function R10 R11 R12 R13 R14 R15 R16 R17 KS0 (Key scan input 0) KS1 (Key scan input 1) KS2 (Key scan input 2) KS3 (Key scan input 3) KS4 (Key scan input 4) KS5 (Key scan input 5) KS6 (Key scan input 6) KS7 (Key scan input 7) Port pin Alternate function R20 R21 R22 R23 AN0 (Analog Input Port0) AN1 (Analog Input Port1) AN2 (Analog Input Port2) AN3 (Analog Input Port3) Port pin Alternate function R31 PWM (PWM Output) |
