The Port A–E Output Control subregister
Control register by writing
Port A–E Output Control subregisters to 1 configures the specified port pins for 
open-drain operation. These subregisters affect the pins directly and, as a result, alternate
functions are also affected.
POC[7:0]—Port Output Control
These bits function independently of the alternate function bit and always disable the
drains if set to 1.
0 = The drains are enabled for any output mode (unless overridden by the alternate
function).
1 = The drain of the associated pin is disabled (open-drain mode).
The Port A–E High Drive Enable subregister
A–E Control register by writing
the Port A–E High Drive Enable subregisters to 1 configures the specified port pins for
high-current output drive operation. The Port A–E High Drive Enable subregister affects
the pins directly and, as a result, alternate functions are also affected.
