1: When TMRx = PRx, the next clock clears TMRx, regardless of the operating mode.
2: In all operating modes, TxON = 0 stops the counter without affecting the value of TMRx
3: In edge-triggered one-shot and monostable modes (not “SW Start” mode), the triggered-start mechanism is reset and
rearmed (prepared for next start) if TxON becomes ‘0’ (zero); the counter will not restart until an input edge occurs.
4: When TMRx = PRx, the next clock clears TxON.
5: When TMRx = PRx, TxON is not cleared.
6: Both TxON and TMRx_ers are subject to clock sync delays.
