TIMEN enables the timer. When the timer is disabled, only the
registers are accessible. Clearing TIMEN reduces power
consumption.
TFFCA enables fast clearing of the main timer interrupt flag registers
(TIMFLG1 and TIMFLG2) and the PA Flag Register (TIMPAFLG).
TFFCA eliminates the software overhead of a separate clear
sequence.
When TFFCA is set:
Writing logic 1s to the flags clears them only when TFFCA is clear.

An input capture read or a write to an output compare channel
clears the corresponding channel flag, CxF.
Any access of the timer count registers (TIMCNTH/L) clears the
TOF flag.
Any access of the PA counter registers (TIMPACNT) clears
both the PAOVF and PAIF flags in TIMPAFLG.
