T1ACP0
Selecting to have a TM input/output or whether to retain its other shared function, is implemented
using one or two registers, with a single bit in each register corresponding to a TM input/output pin.
Setting the bit high will setup the corresponding pin as a TM input/output, if reset to zero the pin will
retain its original other function.
