(2) Port registers (P0 to P7, P12 to P14)
132
Symbol
P12
P13
P14
Note “0” is always read from the output latch of P121 to P124 if the pin is in the external clock input mode.
These registers write the data that is output from the chip when data is output from a port.
If the data is read in the input mode, the pin level is read. If it is read in the output mode, the value of the output
latch is read.
These registers can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets these registers to 00H.
