Refer to 14.2.5 Notes on Tim er RB for precautions regarding bits TSTART, TCSTF and TSTOP.
When the TSTOP bit is set to 1, registers TRBPRE, TRBSC, TRBPR, and bits TSTART and TCSTF, and the TOSSTF bit
in the TRBOCR register are set to values after a reset.
Indicates that count operation is in progress in timer mode or programmable w aveform mode. In programmable one-
shot generation mode or programmable w ait one-shot generation mode, indicates that a one-shot pulse trigger has
been acknow ledged.
When 1 is set to the TSTOP bit in the TRBCR register, the TOSSTF bit is set to 0.
This register is enabled w hen bits TMOD1 to TMOD0 in the TRBMR register is set to 10b (programmable one-shot
generation mode) or 11b (programmable w ait one-shot generation mode).
