16.3.2.14 Timer Input Capture/Output Compare Registers High and Low 0–7
Depending on the TIOS bit for the corresponding channel, these registers are used to latch the value of the
free-running counter when a defined transition is sensed by the corresponding input capture edge detector
or to trigger an output action for output compare.
Read: Anytime
Write: Anytime for output compare function.Writes to these registers have no meaning or effect during
input capture. All timer input capture/output compare registers are reset to 0x0000.

Timer Overflow Flag — Set when 16-bit free-running timer overflows from 0xFFFF to 0x0000. Clearing this bit
requires writing a one to bit 7 of TFLG2 register while the TEN bit of TSCR1 or PAEN bit of PACTL is set to one
(See also TCRE control bit explanation.)
0x0012 = TC1H
0x0014 = TC2H
0x0016 = TC3H
0x0013 = TC1L
0x0015 = TC2L
0x0017 = TC3L
(TCxH and TCxL)
Read/Write access in byte mode for high byte should takes place before low
byte otherwise it will give a different result.
