(2) Port registers (P0, P1, P2, P5)
68
Symbol
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 input clears these registers to 00H (but P2 is undefined).
