You must use software to enable an SPI channel. Until you enable this channel, inputs to it are ignored and outputs to
it are 3-stated.
2
The Debug signals are intended for use during any debug efforts. You can also configure these signals for use as a
second UART channel.
3
The Auxiliary outputs are 3-stated on power-up until they are written to the first time. During this condition, you
should provide pullups or pulldowns to keep any external logic disabled.
