Section 35
35.1.2
PADR is a register that stores data for pins PTA7 to PTA0. Bits PA7DT to PA0DT correspond to
pins PTA7 to PTA0. 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.
