7. I/O Ports
Port A Data Register (PADR): PADR is an 8-bit readable/writable register that stores output
data for port A. When port A functions as an output port, the value of this register is output. When
a bit in PADDR is set to 1, if port A is read the value of the corresponding PADR bit is returned.
When a bit in PADDR is cleared to 0, if port A is read the corresponding pin logic level is read.
PADR is initialized to H'00 by a reset and in hardware standby mode. In software standby mode it
retains its previous setting.
