Table 1.13 Pin Functions for the 80-Pin Package (1/2)
Signal Name Pin Name I/O Power Supply Description
Power supply
input
VCC1,
VSS
I - Apply 1.8 to 5.5 V to the VCC1 pin and 0 V to the VSS pin.
Analog power
supply input
AVCC,
AVSS
I VCC1
This is the power supply for the A/D and D/A converters.
Connect the AVCC pin to VCC1, and connect the AVSS pin
to VSS.
Reset input
RESET I VCC1 Driving this pin low resets the MCU.
CNVSS CNVSS I VCC1
Input pin to switch processor modes. After a reset, to start
operating in single-chip mode, connect the CNVSS pin to
VSS via a resistor.
Main clock input XIN I VCC1 I/O pins for the main clock oscillator. Connect a ceramic
resonator or crystal between pins XIN and XOUT.
(1)
Input
an external clock to XIN pin and leave XOUT pin open.
Main clock output XOUT O VCC1
Sub clock input XCIN I VCC1 I/O pins for a sub clock oscillator. Connect a crystal between
XCIN pin and XCOUT pin.
(1)
Input an external clock to XCIN
pin and leave XCOUT pin open.
Sub clock output XCOUT O VCC1
Clock output CLKOUT O VCC1 Outputs a clock with the same frequency as fC, f1, f8, or f32.

input
NMI I VCC1 Input for the NMI interrupt.
Key input
interrupt input
KI0 to KI7 I VCC1 Input for the key input interrupt.
Timer A
TA0OUT,
TA3OUT,
TA4OUT
I/O VCC1
I/O for timers A0, A3, and A4 (TA0OUT is N-channel open
drain output).
