14.3.2.12 Main Timer Interrupt Flag 1 (TFLG1)
Read: Anytime
Write: Used in the clearing mechanism (set bits cause corresponding bits to be cleared). Writing a zero
will not affect current status of the bit.
14.3.2.13 Main Timer Interrupt Flag 2 (TFLG2)
TFLG2 indicates when interrupt conditions have occurred. To clear a bit in the flag register, write the bit
to one while TEN bit of TSCR1 or PAEN bit of PACTL is set 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.

Input Capture/Output Compare Channel “x” Flag — These flags are set when an input capture or output
compare event occurs. Clearing requires writing a one to the corresponding flag bit while TEN or PAEN is set to
one.
When TFFCA bit in TSCR register is set, a read from an input capture or a write into an output compare channel
(0x0010–0x001F) will cause the corresponding channel flag CxF to be cleared.
