18.5 Port C
18.5.1 Port C Data Register (PTC)
MC68HC908SR12•MC68HC08SR12 — Rev. 5.0
Freescale Semiconductor
NOTE:
Alternative Function:
Additional Function: LED drive LED drive LED drive LED drive LED drive
Address:
Port C is an 8-bit special function port that shares three of its port pins
with the pulse width modulator module, five of its port pins with the
analog-to-digital converter module, and one of its pins with the analog
module. See
Analog-to-Digital Converter
PTC7–PTC3 pins can be configured for direct LED drive.
The port C data register contains a data latch for each of the six port C
pins.
Bit 7 and bit 6 of PTC are not available in a 42-pin shrink dual in-line
package.
PTC[7:0] — Port C Data Bits

Read:
Write:
These read/write bits are software programmable. Data direction of
each port C pin is under the control of the corresponding bit in data
direction register C. Reset has no effect on port C data.
