REJ03B0255-0110 Rev.1.10 Page 19 of 123 Jun 23, 2010 R32C/118 Group 1. Overview 1.5 Pin Definitions and Functions Table 1.14 to Table 1.18 show the pin definitions and functions. Notes: 1. Pins INT6 to INT8 are available in the 144-pin package only. 2. Pins D16 to D31 are available in the 144-pin package only. Table 1.14 Pin Definitions and Functions (1/4) Function Symbol I/O Description Power supply VCC, VSS I Applicable as follows: VCC = 3.0 to 5.5 V, VSS = 0 V Connecting pins for decoupling capacitor VDC0, VDC1 — A decoupling capacitor for internal voltage should be connected between VDC0 and VDC1 Analog power supply AVCC, AVSS I Power supply for the A/D converter. AVCC and AVSS should be connected to VCC and VSS, respectively Reset input RESET I The MCU is reset when this pin is driven low CNVSS CNVSS I This pin should be connected to VSS via a resistor Debug port NSD I/O This pin is to communicate with a debugger. It should be connected to VCC via a resistor of 1 to 4.7 k Ω Main clock input XIN I Input/output for the main clock oscillator. A crystal, or a ceramic resonator should be connected between pins XIN and XOUT. An external clock should be input at the XIN while leaving the XOUT open Main clock output XOUT O Sub clock input XCIN I Input/output for the sub clock oscillator. A crystal oscillator should be connected between pins XCIN and XCOUT. An external clock should be input at the XCIN while leaving the XCOUT open Sub clock output XCOUT O BCLK output BCLK O BCLK output Clock output CLKOUT O Output of the clock with the same frequency as low speed clocks, f8, or f32 External interrupt input INT0 to INT8 (1) I Input for external interrupts NMI input P8_5/ NMI I Input for NMI Key input interrupt KI0 to KI3 I Input for the key input interrupt Bus control pins D0 to D7 I/O Input/output of data (D0 to D7) while accessing an external memory space with a separate bus D8 to D15 I/O Input/output of data (D8 to D15) while accessing an external memory space with 16-bit or 32-bit separate bus D16 to D31 (2) I/O Input/output of data (D16 to D31) while accessing an external memory space with 32-bit separate bus A0 to A23 O Output of address bits A0 to A23 A0/D0 to A7/D7 I/O Output of address bits (A0 to A7) and input/output of data (D0 to D7) by time-division while accessing an external memory space with multiplexed bus A8/D8 to A15/D15 I/O Output of address bits (A8 to A15) and input/output of data (D8 to D15) by time-division while accessing an external memory space with 16-bit or 32-bit multiplexed bus |
