16.5.3 Port C Input Pullup Enable Register
MC68HC908GR8 — Rev 4.0
MOTOROLA
Address:
The port C input pullup enable register (PTCPUE) contains a software
configurable pullup device for each of the two port C pins. Each bit is
individually configurable and requires that the data direction register,
DDRC, bit be configured as an input. Each pullup is automatically and
dynamically disabled when a port bit’s DDRC is configured for output
mode.
