Bit 4 = ICF2 Input capture flag 2
Bit 3 = OCF2 Output compare flag 2
Bit 2 = TIMD Timer disable
Bits 1:0 = Reserved, must be kept cleared
Timer A input capture 1 high register (TAIC1HR)
Reset value: undefined
This is an 8-bit read-only register that contains the high part of the counter value (transferred
by the input capture 1 event).
Timer A input capture 1 low register (TAIC1LR)
Reset value: undefined
This is an 8-bit read-only register that contains the low part of the counter value (transferred
by the input capture 1 event).
MSB
MSB
0: No input capture (reset value)
1: An input capture has occurred on the ICAP2 pin. To clear this bit, first read the SR
register, then read or write the low byte of the IC2R (IC2LR) register.
0: No match (reset value)
1: The content of the free running counter has matched the content of the OC2R
register. To clear this bit, first read the SR register, then read or write the low byte of
the OC2R (OC2LR) register.
This bit is set and cleared by software. When set, it freezes the timer prescaler and
counter and disables 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
