Port A data direction 7 to 0
These bits select input or
output for port A pins
Port A is multiplexed with pins TP₇ to TP₀. Bits corresponding to pins used for TPC output must
be set to 1. For further information about PADDR, see section 8.7, Port A.
11.2.2 Port A Data Register (PADR)
PADR is an 8-bit readable/writable register that stores TPC output data for groups 0 and 1, when
these TPC output groups are used.

These bits store output data
for TPC output groups 0 and 1
Note: * Bits selected for TPC output by NDERA settings become read-only bits.
For further information about PADR, see section 8.7, Port A.
