15.3.2.10 Pull Control Register (PUCR)
Read: Anytime (provided this register is in the map).
Write: Anytime (provided this register is in the map).
This register is used to select pull resistors for the pins associated with the core ports. Pull resistors are
assigned on a per-port basis and apply to any pin in the corresponding port that is currently configured as
an input. The polarity of these pull resistors is determined by chip integration. Please refer to the device
overview chapter to determine the polarity of these resistors.

No writes to the MOD bits are allowed while operating in a secure mode. For more details, refer to the device
overview chapter.
If you are in a special single-chip or special test mode and you write to this register, changing to normal sin-
gle-chip mode, then one allowed write to this register remains. If you write to normal expanded or emulation
mode, then no writes remain.
