Chapter 6 Timer Module (TIM16B4CV1)
6.3.2.13
TFLG2 indicates when interrupt conditions have occurred. To clear a bit in the flag register, write the bit
to one.
Read: Anytime
Write: Used in clearing mechanism (set bits cause corresponding bits to be cleared).
Any access to TCNT will clear TFLG2 register if the TFFCA bit in TSCR register is set.
6.3.2.14
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.

Timer Overflow Flag — Set when 16-bit free-running timer overflows from 0xFFFF to 0x0000. This bit is cleared
automatically by a write to the TFLG2 register with bit 7 set. (See also TCRE control bit explanation.)
