I/O ports P50 to P53
• Input or output in 4-bit or 1-bit units
• Input or output in 8-bit units when used
in conjunction with P40 to P43.
• Can be used for output of 8-bit ROM
data when used in conjunction with
P40 to P43.
• P53 is also used as the INT2 interrupt
request.
I/O ports P60 to P63
• Input or output in 4-bit or 1-bit units
• P60 is also used as the melody output
ML pin.
• P62 is also used as the tone output DT
pin.
• P63 is also used for the event count
input to timer 1.
I/O ports PC2 to PC3
Output in 2-bit or 1-bit units
Dedicated input ports PD0 to PD3

Dedicated input ports
System clock oscillator connections
When an external clock is used, leave
OSC2 open and connect the clock signal
to OSC1.
System reset input
When the P33/HOLD pin is at the high
level, a low level input to the RES pin will
initialize the CPU.
CPU test pin
This pin must be connected to VSS
during normal operation.
