Input/Output (I/O) Ports
16.3.3 Port A Input Pullup Enable Register
Technical Data
218
Address:
The port A input pullup enable register (PTAPUE) contains a software
configurable pullup device for each of the eight port A pins. Each bit is
individually configurable and requires that the data direction register,
DDRA, bit be configured as an input. Each pullup is automatically and
dynamically disabled when a port bit’s DDRA is configured for output
mode.
PTAPUE7–PTAPUE0 — Port A Input Pullup Enable Bits
Reset:
Read:
Write:
These writable bits are software programmable to enable pullup
devices on an input port bit.
