Input/Output Ports (I/O)
16.6.3 Port D Input Pullup Enable Register
Technical Data
224
Address:
Reset:
The port D input pullup enable register (PTDPUE) contains a software
configurable pullup device for each of the seven port D pins. Each bit is
individually configurable and requires that the data direction register,
DDRD, bit be configured as an input. Each pullup is automatically and
dynamically disabled when a port bit’s DDRD is configured for output
mode.

Freescale Semiconductor, Inc.
These writeable bits are software programmable to enable pullup
devices on an input port bit.
