7.14.4 Port A Registers
Port A has four memory-mapped, read-write, 16-bit control registers.
7.14.4.1 PORT A OPEN-DRAIN REGISTER (PAODR). The PAODR indicates a normal or
wired-OR configuration of the port pins. Six of the PAODR bits can be open-drain to corre-
spond to those pins that have serial channel output capability. The other bits are always
zero. PAODR is cleared at system reset.
For each ODx bit, the definition is as follows:
7.14.4.2 PORT A DATA REGISTER (PADAT). A read of PADAT returns the data at the
pin, independent of whether the pin is defined as an input or an output. This allows detection
of output conflicts at the pin by comparing the written data with the data on the pin. A write
to the PADIR is latched, and if that bit in the PADIR is configured as an output, the value
latched for that bit will be driven onto its respective pin. PADAT can be read or written at any
time. PADAT is not initialized and is undefined at reset.
7.14.4.3 PORT A DATA DIRECTION REGISTER (PADIR). PADIR is cleared at system
reset.
For each DRx bit, the definition is as follows:
7.14.4.4 PORT A PIN ASSIGNMENT REGISTER (PAPAR). PAPAR is cleared at system
reset.

0 = The I/O pin is actively driven as an output.
1 = The I/O pin is an open-drain driver. As an output, the pin is actively driven low, but
0 = The corresponding pin is an input.
1 = The corresponding pin is an output.
