Section 9 I/O Ports
PADR is an 8-bit readable/writable register that stores output data for the port A pins (PA5 to
PA0).
Bits 7 and 6 are reserved; they return an undetermined value if read, and cannot be modified.
PADR is initialized to H'0 (bits 5 to 0) by a reset, and in hardware standby mode. It retains its
prior state in software standby mode.
Port A Register (PORTA)
Notes: 1. Determined by state of pins PA5 to PA0.
PORTA is an 8-bit read-only register that shows the pin states. It cannot be written to. Writing of
output data for the port A pins (PA5 to PA0) must always be performed on PADR.
Bits 7 and 6 are reserved; they return an undetermined value if read, and cannot be modified.
If a port A read is performed while PADDR bits are set to 1, the PADR values are read. If a port A
read is performed while PADDR bits are cleared to 0, the pin states are read.
After a reset and in hardware standby mode, PORTA contents are determined by the pin states, as
PADDR and PADR are initialized. PORTA retains its prior state in software standby mode.
Port A MOS Pull-Up Control Register (PAPCR)
Note:
PAPCR is an 8-bit readable/writable register that controls the MOS input pull-up function
incorporated into port A on an individual bit basis.
