Read: Anytime; read pin state when corresponding TIMDDR bit is 0;
read pin driver state when corresponding TIMDDR bit is 1
Write: Anytime
= Writes have no effect and the access terminates without a transfer error exception.

PORTT[3:0] — Timer Port Input Capture/Output Compare Data Bits
Data written to TIMPORT is buffered and drives the pins only when
they are configured as general-purpose outputs.
Reading an input (DDR bit = 0) reads the pin state; reading an output
(DDR bit = 1) reads the latch.
Writing to a pin configured as a timer output does not change the pin
state.
