Address:
Reset:
The port D input pullup enable register (PTDPUE) contains a software
configurable pullup device for each of the eight 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.
PTDPUE7–PTDPUE0 — Port D Input Pullup Enable Bits
Port E is a 2-bit special-function port that shares two of its pins with the
serial communications interface (SCI) module.
