TCMP : Timer Compared Value\nTCMP is a 24-bit compared value register. When the internal 24-bit up counter value is equal to TCMP value, the TIF (TISR[0] timet interrupt flag) will set to 1.\nNote1: Never write 0x0 or 0x1 in TCMP field, or the core will run into unknown state.\nNote2: When timer is operating at continuous counting mode, the 24-bit up counter will keep counting continuously even if software writes a new value into TCMP field. But if timer is operating at other modes, the 24-bit up counter will restart counting and using newest TCMP value to be the timer compared value if software writes a new value into TCMP field.
