Reset — This input is a direct hardware reset on the processor.
When RESET is asserted low, the device is initialized and placed in
the reset state. A Schmitt-trigger input is used for noise immunity.
The internal reset signal is deasserted synchronous with the
internal clocks after a fixed number of internal clocks.

Port A GPIO — This GPIO pin can be individually programmed as
an input or output pin. RESET functionality is disabled in this mode
and the chip can be reset only via POR, COP reset, or software
reset.
