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
These two bits select between four programmable drive levels. Each pin is individually
programmable.
LEDLVLH[7:0]—LED Level High Bit
{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
The LED Drive Level registers contain two control bits for each Port C pin
These two bits select between four programmable drive levels. Each pin is individually
programmable.
