• When the timer underflows, the contents of the reload register are reloaded
n: Value set in TRAPRE register, m: Value set in TRA register
1 (count starts) is written to the TSTART bit in the TRACR register.
• 1 (count forcibly stops) is written to the TSTOP bit in the TRACR register.
When timer RA underflows [timer RA interrupt].
The count value can be read by reading registers TRA and TRAPRE.
• When registers TRAPRE and TRA are written during the count, values are
1/(n+1)(m+1)
• 0 (count stops) is written to the TSTART bit in the TRACR register.
