6.1.1 Port 32A

Port 32A on the XS1-L device is a 32-bit wide port that has several separate signal
bit signal connected to it, accessed by multiple cores. To this end, any output
to this port must be read-modify-write i.e. to change a single bit of the port, the
software reads the current value being driven across 32 bits, flips a bit and then
outputs the modified value.
