The three least significant bits are not used.
Bit 7 = ICF1 Input Capture Flag 1.
0: No input capture (reset value).
1: An input capture has occurred on the ICAP1 pin
Bit 6 = OCF1 Output Compare Flag 1.
0: No match (reset value).
1: The content of the free running counter has
Bit 5 = TOF Timer Overflow Flag.
0: No timer overflow (reset value).

Bit 2 = TIMD Timer disable.
This bit is set and cleared by software. When set, it
freezes the timer prescaler and counter and disa-
bled the output functions (OCMP1 and OCMP2
pins) to reduce power consumption. Access to the
timer registers is still available, allowing the timer
configuration to be changed while it is disabled.
0: Timer enabled
1: Timer prescaler, counter and outputs disabled
