8 / 51 page R8C/M13B Group 1. Overview R01DS0005EJ0100 Rev.1.00 Page 8 of 48 Mar 14, 2011 1.5 Pin Functions Tables 1.5 and 1.6 list Pin Functions. Note: 1. Contact the oscillator manufacturer for oscillation characteristics. Table 1.5 Pin Functions (1) Item Pin Name I/O Description Power supply input VCC, VSS — Apply 1.8 V through 5.5 V to the VCC pin. Apply 0 V to the VSS pin. Analog power supply input AVCC, AVSS — Power supply input for the A/D converter. Connect a capacitor between pins AVCC and AVSS. Reset input RESET I Applying a low level to this pin resets the MCU. MODE MODE I Connect this pin to the VCC pin via a resistor. XIN clock input XIN I I/O for the XIN clock generation circuit. Connect a ceramic resonator or a crystal oscillator between pins XIN and XOUT. (1) To use an external clock, input it to the XIN pin. P4_5 can be used as an I/O port at this time. XIN clock output XOUT O XCIN clock input XCIN I I/O for the XCIN clock generation circuit. Connect a crystal oscillator between pins XCIN and XCOUT. (1) To use an external clock, input it to the XCIN pin. P4_7 can be used as an I/O port at this time. XCIN clock output XCOUT O INT interrupt input INT0 to INT3 I INT interrupt input. Key input interrupt KI0 to KI3 I Key input interrupt input. I/O ports P0_0 to P0_7, P1_0 to P1_7, P2_0 to P2_2, P3_1, P3_3 to P3_5, P3_7, P4_2, P4_5 to P4_7, PA_0 I/O CMOS I/O ports. Each port has an I/O select direction register, enabling switching input and output for each port. For input ports other than PA_0, the presence or absence of a pull-up resistor can be selected by a program. P1_2 to P1_5, P3_3 to P3_5, and P3_7 can be used as LED drive ports. Timer RJ2 TRJIO I/O Timer RJ2 I/O. TRJO O Timer RJ2 output. Timer RB2 TRBO O Timer RB2 output. Timer RC TRCCLK I External clock input. TRCTRG I External trigger input. TRCIOA, TRCIOB, TRCIOC, TRCIOD I/O Timer RC I/O. Timer RK TRKI I Timer RK external input. TRKO O Timer RK output. Timer RE2 TREO O Timer RE2 output. Serial interface CLK0, CLK1 I/O Transfer clock I/O. RXD0, RXD1 I Serial data input. TXD0, TXD1 O Serial data output. Synchronous serial communication unit (SSU) SSI I/O Data I/O. SCS I/O Chip-select signal I/O. SSO I/O Data I/O. SSCK I/O Clock I/O. I2C bus interface SDA I/O Data I/O. SCL I/O Clock I/O. IrDA Interface IrRXD I Data input. IrTXD O Data output. A/D converter AN0 to AN7 I Analog input for the A/D converter. ADTRG I External trigger input for the A/D converter. |
