Section 18 I/O Ports
18.1.2
Port A data Register (PADR) is an 8-bit read/write register that stores data for pins PTA7 to
PTA0. PA7DT to PA0DT bit corresponds to PTA7 to PTA0 pin. When the pin function is general
output port, if the port is read the value of the corresponding PADR bit is returned directly. When
the function is general input port, if the port is read the corresponding pin level is read.
