The Port A–E Output Data register
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 
The LED Drive Enable register
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 synch to Port C pin.
The LED Drive Level Registers consist of two registers: LED Drive Level High Bit 
Register—LEDLVLH[7:0] and LED Drive Level Low Bit Register—LEDLVLL[7:0] (see
setting the corresponding Port Output Control register bit to 1.
