(2) Port 1A
Whether a resistor is connected to each bit of port P1A when a key matrix is not used can be specified in 1-
bit units by using the following register fileNote.
To connect a resistor, select whether a pull-down or pull-up resistor is to be connected, by using P1AHL
(address 05H) of the register file.
