Capture/Compare Unit 6 (CCU6)
• with the next T12 clock (
f
T12
) after a compare-match when T12 is counting up (i.e., when the counter is
incremented above the compare value);
• with the next T12 clock (
f
T12
) after a zero-match AND a parallel compare-match when T12 is counting up.
A State Bit
CC6xST is cleared
to 0:
• with the next T12 clock (
f
T12
) after a compare-match when T12 is counting down (i.e., when the counter is
decremented below the compare value in center-aligned mode);
• with the next T12 clock (
f
T12
) after a zero-match AND NO parallel compare-match when T12 is counting up.
Figure 129 Compare Operation, Edge-Aligned Mode
illustrates some more examples for compare waveforms. It is important to note that in these
examples, it is assumed that some of the compare values are changed while the timer is running. This change
is performed via a software preload of the Shadow Register, CC6xSR. The value is transferred to the actual
Compare Register CC6xR with the T12 Shadow Transfer signal, T12_ST, that is assumed to be enabled.
