Apply 2.7 to 5.5 V to the VCC1 and VCC2 pins and 0 V to the V
pin. The VCC apply condition is that VCC1 = VCC2.
Applies the power supply for the A/D converter. Connect the AVCC
pin to VCC1. Connect the AVSS pin to VSS.
The microcomputer is in a reset state when applying “L” to the this
pin.
Connect this pin to VSS.
I/O pins for the main clock generation circuit. Connect a ceramic
resonator or crystal oscillator between XIN and XOUT. To use the
external clock, input the clock from XIN and leave XOUT open.
I/O pins for a sub clock oscillation circuit. Connect a crystal
oscillator between XCIN and XCOUT. To use the external clock,
input the clock from XCIN and leave XCOUT open.
The clock of the same cycle as fC, f8, or f32 is outputted.
Input pins for the INT interrupt.
Input pin for the NMI interrupt.
Input pins for the key input interrupt.
These are timer A0 to timer A2 I/O pins. (except the output of
TA0OUT for the N-channel open drain output.)
These are timer A0 to timer A2 input pins.
These are timer B0 to timer B2 input pins.
These are send control input pins.
These are receive control output pins.
These are transfer clock I/O pins.
These are serial data input pins.
These are serial data output pins. (except TXD2 for the N-channel
open drain output.)
This is output pin for transfer clock output from multiple pins
function.
These are serial data I/O pins. (except SDA2 for the N-channel
open drain output.)
These are transfer clock I/O pins. (except SCL2 for the N-channel
open drain output.)
