NOTES:
1. The contents of the read-out buffer can be read when the TX register is read in pulse period measurement mode.
2. After an active edge of measurement pulse is input, the TXEDG bit in the TXMR register is set to "1" (active edge found)
3. The TX register should be read before the next active edge is input after the TXEDG bit is set to "1" (active edge found).
4. When set to "0" by program, use a MOV instruction to write "0" to the TXEDG in the TXMR register. At the same time,
5. When set to "0" by program, use a MOV instruction to write "0" to the TXUND in the TXMR register. At the same time,
6. The TXUND and TXEDG bits are both set to "1" if the timer underflows and reloads on an active edge simultaneously. In
