8.10
Port A is a 4-bit I/O port that also has other functions. The port A has the following registers.
• Port A data direction register (PADDR)
• Port A data register (PADR)
• Port A register (PORTA)
8.10.1
The individual bits of PADDR specify input or output for the pins of port A. PADDR cannot be
read; if it is, an undefined value will be read.
8.10.2
PADR stores output data for the port A pins.

Description
Reserved
If these bits are read, an undefined value will be read.
These bits cannot be modified.
When a pin function is specified to a general purpose
I/O, setting this bit to 1 makes the corresponding port A
pin an output pin, while clearing this bit to 0 makes the
pin an input pin.
Description
Reserved
If these bits are read, an undefined value will be read.
These bits cannot be modified.
Output data for a pin is stored when the pin function is
specified to a general purpose output.
