6.5.3.1
This register is reset only by the Power-On Reset (POR). It has no part-specific functionality and is
intended for use by a software developer to contain data that will be unaffected by the other reset sources
(RESET pin, software reset, and COP reset).
6.5.4
This read-only register displays the most significant half of the JTAG ID for the chip. This register reads
$11F4.
6.5.5
This read-only register displays the least significant half of the JTAG ID for the chip. This register reads
$401D.
6.5.6
Most of the pins on the chip have on-chip pull-up resistors. Pins which can operate as GPIO can have these
resistors disabled via the GPIO function. Non-GPIO pins can have their pull-ups disabled by setting the
appropriate bit in this register. Disabling pull-ups is done on a peripheral-by-peripheral basis (for pins not
muxed with GPIO). Each bit in the register (see
