18.5.3 Port C LED Control Register (LEDC)
MC68HC908LJ24/LK24 — Rev. 2.1
Freescale Semiconductor
Address:
When DDRCx is a logic 1, reading address $0002 reads the PTCx data
latch. When DDRCx is a logic 0, reading address $0002 reads the
voltage level on the pin. The data latch can always be written, regardless
of the state of its data direction bit.
Table 18-4
Port-C LED control register (LEDC) controls the direct LED drive
capability on PTC7–PTC0 pins. Each bit is individually configurable and
requires that the data direction register, DDRC, bit be configured as an
output.

Notes:
Reset:
1. X = don’t care.
2. Hi-Z = high impedance.
3. Writing affects data register, but does not affect input.

DDRC
These read/write bits are software programmable to enable the direct
LED drive on an output port pin.
