The LED drive enable register activates the controlled current drive. See
Port C pin must first be enabled by setting the alternate function register to select the LED
function. See
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. See
These two bits selects one of four programmable current drive levels for each Port C pin.
Each pin is individually programmable. See
LEDLVLH[7:0]—LED level high bits
{LEDLVLH, LEDLVLL} select one of four programmable current drive levels for each
Port C pin.
00 = 3 mA
01 = 7 mA
10 = 13 mA
11 = 20 mA
