R/W 1: Timer value is captured if required by an IRQ
R/W Compare mode.
R/W 1: RTC2 is enabled. The clock to the RTC2 core
R/W RTC2 compare value register 0.
R/W RTC2 compare value register 1.

from the Radio (edge detect @ MCU clock). The
value is stored in RTC2CPT00 and
RTC2CPT01. An additional counter clocked by
the MCU clock will at this point contain the num-
ber of MCU clock cycles from the previous posi-
tive edge of the 32 KHz clock (edge detect @
MCU clock). The value is stored in RTC2CPT1.
0: Capture by Radio disabled.
11: An interrupt assigned when the timer value
is equal to the concatenation of RTC2CMP1 and
RTC2CMP0. RTC2 ensures that the functions
that the interrupt is meant for are all woken up
prior to the interrupt. The interrupt resets the
timer. Interrupt duration: ½·T
10: Same as above, except from that the inter-
rupt will not reset the timer. The timer will always
wrap around at overflow.
0x: Compare disabled.
functionality is running.
0: RTC2 is disabled. The clock to the RTC2 core
functionality stands still. Outputs are grounded.
Contains LSByte of the value to be compared to
the timer value to generate interrupt. The total
value of RTC2CMP0 and RTC2CMP1 must
always be larger than <rtc2PreCompareValue>.
Resolution: 30.52 µs.
Contains MSByte of the value to be compared to
the timer value to generate interrupt. The total
value of RTC2CMP0 and RTC2CMP1 must
always be larger than <rtc2PreCompareValue>.
RTC2 capture value register 00.
Contains LSByte of the timer value at the time of
the capture event. Resolution: 30.52 µs.
RTC2 capture value register 01.
Contains MSByte of the timer value at the time
of the capture event.
RTC2 capture value register 1.
Contains the value of the counter that counts the
number of MCU clock cycles from the previous
positive edge of the 32 KHz clock until the cap-
ture event. The counter value is truncated by
one bit (LSBit). Resolution: 125 ns.
