Apply 2.7 to 5.5 V to the VCC1 pin and 0 V to the VSS pin.
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.
Switches processor mode. Connect this pin to VSS to when after a
reset to start up in single-chip mode. Connect this pin to VCC1 to
start up in microprocessor mode. As for the BYTE pin of the 80-pin
versions, pull-up processing is performed within the microcomputer.
I/O pins for the main clock generation circuit. Connect a ceramic
resonator or crystal oscillator between XIN and XOUT
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
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,Timer A3 and Timer A4 I/O pins. (however,
output of TA0OUT for the N-channel open drain output.)
These are Timer A0, Timer A3 and Timer A4 input pins.
Input pin for the Z-phase.
These are Timer B0, Timer B2 to Timer B5 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.
This is serial data input pin.
These are serial data output pins. (however, output of TXD2 for
the N-channel open drain output.)
These are serial data output pins.
This is output pin for transfer clock output from multiple pins
function.
These are serial data I/O pins. (however, output of SDA2 for the
N-channel open drain output.)
These are transfer clock I/O pins. (however, output of SCL2 for
the N-channel open drain output.)
