2.3.2.1.1
Read: Anytime.
Write: Anytime.
If the data direction bits of the associated I/O pins are set to 1, a read returns the value of the port register,
otherwise the value at the pins is read.
If a TIM-channel is defined as output, the related port T is assigned to IOC function.
In addition to the possible timer functionality of port T pins PWM channels can be routed to port T. For
this the Module Routing Register (MODRR) needs to be configured.

MODRR[x]
configured for output compare function (TIOS[x] or special output on a timer
overflow event — configurable in TTOV[x]) and the timer output is routed to the
port pin (TCTL1/TCTL2).
