Description
PAODR stores output data for the port A pins that
are used as the general output port.
Description
When a PAPIN read is performed, the pin states
are read.
This register is assigned to the same address as
that of PADDR. When this register is written to,
data is written to PADDR and the port A setting is
then changed.
