Description
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.
Description
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.

The LED Drive Enable Register, shown in Table 31, activates the controlled current drive.
The Alternate Function Register has no control over the LED function; therefore, setting
the Alternate Function Register to select the LED function is not required. LEDEN bits
[7:0] correspond to Port C bits [7:0], respectively.
The LED Drive Level High Register, shown in Table 32, contains two control bits for each
Port C pin. These two bits select one of four programmable current drive levels for each
Port C pin. Each pin is individually programmable.
