Refer to 14.1.6 Notes on Tim er RA.
When the TSTOP bit is set to 1, bits TSTART and TCSTF and registers TRAPRE and TRA are set to the values after a
reset.
Bits TEDGF and TUNDF can be set to 0 by w riting 0 to these bits by a program. How ever, their value remains
unchanged w hen 1 is w ritten.
In pulse w idth measurement mode and pulse period measurement mode, use the MOV instruction to set the TRACR
register. If it is necessary to avoid changing the values of bits TEDGF and TUNDF, w rite 1 to them.
Set to 0 in timer mode, pulse output mode, and event counter mode.
