POUT[7:0]—Port Output Data
These bits contain the data to be driven to the port pins. The values are only driven if the
corresponding pin is configured as an output and the pin is not configured for alternate
function operation.
0 = Drive a logical 0 (Low).
1= Drive a logical 1 (High). High value is not driven if the drain has been disabled by set-
ting the corresponding Port Output Control register bit to 1.
The LED Drive Enable register (Table 28) activates the controlled current drive. The Port
C pin must first be enabled by setting the Alternate Function register to select the LED
function.
LEDEN[7:0]—LED Drive Enable
These bits determine which Port C pins are connected to an internal current sink.
0 = Tristate the Port C pin.
1= Connect controlled current sink to the Port C pin.
The LED Drive Level registers contain two control bits for each Port C pin (Table 29).
These two bits select between four programmable drive levels. Each pin is individually
programmable.
