P10 to P13
P20 to P23
(PI011A block
)
24 to 27
28 to 31
35 to 38
I / O
4-bit input or output.
Input/Output is specified in a bit by program.
(Output is Nch open drain type.)
Pull-up resistor can be turned ON/OFF in a bit by program.
Upon resetting, input is specified, and the pull-up resistance
is turned OFF.
1
D
W0 to W3
(STP04A block
)
43 to 46
I
General 4-bit input.
It can be used as stop cancellation input and interrupt request
signal input by program. (It can be specified in a bit)
Pull-up resistor can be turned ON/OFF in a bit by program.
Upon resetting, the pull-up resistor is turned OFF.
C
BIN
(BIX03A block
)
42
I
General 1-bit input.
It can be used as stop cancellation input and interrupt request
signal input by program.
Pull-up resistor can be turned ON/OFF by program.
Upon resetting, the pull-up resistor is turned OFF.
C
1 Immediately after resetting, terminal is in high impedance state. Therefore, termination may be required in some applications.
