Description
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 is set to one (See also TCRE control
bit explanation.)

Figure 22-23. Timer Input Capture/Output Compare Register x Low (TCxL)
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.
NOTE
Read/Write access in byte mode for high byte should takes place before low
byte otherwise it will give a different result.
