Notes:
1. All writes/reads to/from T2CCC will access channel X as currently selected by T2CCA.The control registers for the remain-
ing unselected channels are not accessible.
2. Analog Comparator A events are determined by the CMA2-0 bits in ACSRA. See Table 18-1 on page 102.
3. Analog Comparator B events are determined by the CMB
2-0 bits in ACSRB. See Table 18-2 on page 103.
4. Asymmetrical versus Symmetrical PWM is determined by the Timer 2 Count Mode. See “Pulse Width Modulation Mode” on
Table 13-4.

Function
CIENx
Channel X Interrupt Enable. When set, channel X’s interrupt flag, CCFx in T2CCF, will generate an interrupt when
ECC = 1. Clear to disable interrupts from channel X.
CDIRx
Channel X Capture Direction. In dual-slope modes, a compare/capture event on channel X will store the current count
direction into CDIRx. Up-counting = 0 and down-counting = 1. Modifying this bit has no effect.
CTCx
Clear Timer on Compare/Capture of Channel X. When set, the Timer 2 registers TL2 and TH2 will be cleared by a
compare/capture event on channel X. When cleared, Timer 2 is unaffected by channel X events.
CCMx
Channel X Compare/Capture Mode. When CCMx = 1, channel X operates in compare mode. When CCMx = 0, channel
X operates in capture mode.
CxM
[2 - 0]
Channel X Mode. Selects the output/input events for compare/capture channel X.
