Pin Name I/O Description Option Port 7 I/O • 4-bit I/O ports • I/O specifiable in 1-bit units • Pull-up resistors can be turned on and off in 1-bit units. • Pin functions P70: INT0 input/HOLD release input/timer 0L capture input/watchdog timer output P71: INT1 input/HOLD release input/timer 0H capture input P72: INT2 input/HOLD release input/timer 0 event input/timer 0L capture input/ high speed clock counter input P73: INT3 input (input with noise filter)/timer 0 event input/timer 0H capture input/ infrared remote control receiver input AD converter input ports: AN8(P70), AN9(P71) Interrupt acknowledge types No P70 to P73 Rising Falling Rising & Falling H level L level INT0 enable enable disable enable enable INT1 enable enable disable enable enable INT2 enable enable enable disable disable INT3 enable enable enable disable disable PWM0 PWM1 I/O PWM0, PWM1 output ports General-purpose input port • Pin functions PWM0: Audio interface master clock output PWM1: Audio interface master clock input No UHD- I/O USB data I/O pin UHD-/general-purpose I/O port No UHD+ I/O USB data I/O pin UHD+/general-purpose I/O port No RES I Reset pin No XT1 I • 32.768kHz crystal oscillator input • Pin functions General-purpose input port AD converter input port: AN10 Must be connected to VDD1 when not to be used. No XT2 I/O • 32.768kHz crystal oscillator output • Pin functions General-purpose input port AD converter input port: AN11 Must be configured for oscillation and kept open if not to be used. No CF1 I Ceramic/crystal resonator input No CF2 O Ceramic/crystal resonator output No Port Output Types The table below lists the types of port outputs and the presence/absence of a pull-up resistor. Data can be read into any input port even if it is in the output mode. Port Name Option Selected in Units of Option Type Output Type Pull-up Resistor P00 to P07 1 bit 1 CMOS Programmable (Note 1) 2 Nch-open drain No P10 to P17 P20 to P27 P30 to P34 1 bit 1 CMOS Programmable 2 Nch-open drain Programmable P70 - No Nch-open drain Programmable P71 to P73 - No CMOS Programmable PWM0, PWM1 - No CMOS No UHD+, UHD- - No CMOS No XT1 - No Input only No XT2 - No 32.768kHz crystal resonator output (Nch-open drain when in general-purpose output mode) No Note 1: Programmable pull-up resistors for port 0 are controlled in 4 bit units (P00 to 03, P04 to 07). |
