The oscillation circuit is built in the P20/XOUT/XCOUT pin and the P21/XIN/XCIN pin. When the Vcc of the microcomputer is lower than the operation lower bound voltage even if these pins are used as I/O ports, the oscillation circuit is connected and undefined values may be output from these pins. Table 2 Pin description Pin Name Function Function expect a port function VCC,VSS Power source Apply voltage of 1.8 to 5.5 V to Vcc, and 0 V to Vss. CNVSS CNVSS Controls the operation mode of the chip. Connected to VSS. RESET Reset input Reset input pin for active “L” P00(LED0)/INT0 P01(LED1)/INT1 I/O port P0 •8-bit I/O port. •I/O direction register allows each pin to be individu- ally programmed as either input or output. •CMOS compatible input level •CMOS 3-state output structure •Whether a built-in pull-up resistor is to be used or not can be determined by program. •High drive capacity for LED drive port can be selected by program. Interrupt input pin P02(LED2) P03(LED3)/CAP0 Capture input pin P04(LED4)/RXD P05(LED5)/TXD P06(LED6)/SCLK P07(LED7)/SRDY Serial interface function pin P10/AN0/KEY0/CMP0 P11/AN1/KEY1/CMP1 P12/AN2/KEY2/CMP2 I/O port P1 •8-bit I/O port. •I/O direction register allows each pin to be individu- ally programmed as either input or output. •CMOS compatible input level •CMOS 3-state output structure •Whether a built-in pull-up resistor is to be used or not can be determined by program. Input pins for A/D converter Key-input (key-on wake up interrupt input) pin Compare output pin P13/AN3/KEY3/T2OUT Timer 2 output pin P14/AN4/KEY4 P15/AN5/KEY5 P16/AN6/KEY6 P17/AN7/KEY7 P20/XOUT/XCOUT P21/XIN/XCIN (Note) I/O port P2 •2-bit I/O port. (P20/XOUT/XCOUT is only for output) •I/O direction register allows each pin to be individu- ally programmed as either input or output. •CMOS compatible input level •CMOS 3-state output structure •Function set ROM allows pins to be used as clock pins. Pins XIN and XOUT, or pins XCIN and XCOUT, can be used as clock pins by connecting a ceramic resonator, crystal oscillator, or 32 kHz crystal oscillator between them. Alternately, an external clock may be input to the P20/XOUT/XCOUT pin. In this case, the P21/XIN/XCIN pin can be used as an I/O port. P30, P31 I/O port P3 •2-bit I/O port. •I/O direction register allows each pin to be individually programmed as either input or output. •CMOS compatible input level •CMOS 3-state output structure |
