Apply a voltage of 2.7 to 5.5 V to VCC and 0 V to VSS and AVSS.
Reference voltage input pin for A-D converter.

Used as CE input pin.
Reset input pin.
Connect to VSS.
These are I/O pins of internal clock generating circuit for the main
clock. To control generating frequency, an external ceramic resona-
tor is connected between XIN and XOUT pins. If an external clock is
used, the clock oscillation source should be connected to the XIN
pin, and the XOUT pin should be left open. Feedback resistor is con-
nected between XIN and XOUT.
8-bit I/O port. The output structure is CMOS output.
When this port is selected for input, a pull-up transistor can be con-
nected in units of 1 bit, and a key-on wake-up function is provided.
Data 8-bit (D0 to D7) I/O pins
8-bit I/O port. The output structure is CMOS output.
When this port is selected for input, a pull-up transistor can be con-
nected in units of 4 bits. P12 and P13 are in common with timer
output pins T0 and T1. P14, P15, P16 and P17 are in common with
____
serial I/O pins RxD, TxD, SCLK and SRDY.
P11 to P17 are address (A4 to A10) input pins. Leave P10 open.
8-bit input port. This port is in common with analog input pins IN0 to
IN7 (IN0 to IN3 for the 7480 group).
P20 to P23 are address (A0 to A3) input pins. Leave P24 to P27
open.
4-bit input port. P30 and P31 are in common with external interrupt
input pins INT0 and INT1.
__
P30 and P31 are address (A11, A12) input pins. P32 is used for OE
input. P33 is VPP input. Apply VPP in the program and program
verify modes.
4-bit I/O port. The output structure is N-channel open drain output,
having built-in clamp diode. P40 and P41 are in common with timer
input pins CNTR0 and CNTR1.
P40 and P41 are address (A13, A14) input pins. Leave P42 and P43
open.
