Description
The corresponding port 6 pins are output ports
when P6DDR bits are set to 1, and input ports
when cleared to 0.
Description
If a port 6 read is performed while P6DDR bits are
set to 1, the P6DR values are read directly,
regardless of the actual pin states. If a port 6 read
is performed while P6DDR bits are cleared to 0,
the pin states are read.
