LED Drive Level High Register
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 = Enable controlled current sink on the Port C pin.
Note: x indicates the specific GPIO port pin number (7–0).
Description
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 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 registers contain two control bits for each Port C pin, as shown in
Table 32. These two bits select between four programmable drive levels. Each pin is indi-
vidually programmable.
