Apply 2.00 V to 5.5 V to the Vcc1 and Vcc2 pins. Apply 0 V to the Vss
pin. Input condition of Vcc1 and Vcc2 are Vcc1 ≤ Vcc2. ^(1.)
VCC2 Connect this pin to VSS.
VCC2 "L" on this input resets the microcomputer.
VCC2 These are I/O pins provided for main clock oscillation circuit.
Connect ceramic resonator or crystal oscillator between pins XIN and
XOUT. To use an externally derived clock, input it to XIN pin and leave

This pin is a power supply input for the A/D converter. Connect this pin to VCC.
This pin is a power supply input for the A/D converter. Connect this pin to VSS.
This is an 8-bit CMOS I/O port. This port has an I/O select direction register,
allowing each pin in that port to be directed for input or output individually.
If any port is set for input, selection can be made for it in a program whether or
not to have a pull-up resistor in 4 bit units. Pins in this oprt also function as
A/D converter input pins as selected by Program.
P10 to P17 I/O port P1
Input/output VCC2
This is an 8-bit I/O port equivalent to P0. Pins P15 to P17 in this port also
functionas INT interrupt input pins as selected by software.
P20 to P27 I/O port P2
Input/output VCC2 This is an 8-bit I/O port equivalent to P0.
Note 1: In this datasheet, hereafter, VCC refers to VCC2 unless otherwise noted.
