TM Input/Output Pin Control Register
Selecting to have a TM input/output or whether to retain its other shared function is implemented
using one register, with a single bit in the 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.
