I/O Input/output port pins P30 to P32
· Pch: CMOS type
· Used for input/output operation in 3-bit · Nch: Small sink current
units or bit units and for input operation

for Nch OD output
· P30 : Common with INT1 interrupt
request input
· P31 : Common with burst pulse output
from timer 0
· P32 : Common with burst pulse output
from timer 1 and PWM output
I HOLD mode control signal input
· Used for activating HOLD operation
mode with HOLD = L (active low) by
using a HOLD instruction.
· Used for restarting the CPU operation
from the HOLD mode operation by
changing the HOLD pin level from L to
H.
· Used as input port pin P33 to form a 4-
bit input port with P30 to P32.
· The CPU blocks cannot be reset even if
the RES (active low) pin level changes
from H to L, with the HOLD pin level
= L. This means that you cannot write
a user application program requiring
the P33/HOLD pin to enter the L level
state at the moment the system is
powered on.
I/O Input/output port pins P40 to P43
· Pch: Pull-up (Pu) MOS
· Used for input/output operation in 4-bit
units or bit units.
· These four pins, combined with port
pins P50 to P53, can be used for
type
· Nch: Small sink current
output type
input/output operation in 8-bit units.
· These four pins, together with port pins
P50 to P53, can be used for 8-bit
ROM data output.
