Only the first 16 bits (channel counter size) of field CV are significant.
• CV: Comparison x Value
Define the comparison x value to be compared with the counter of the channel 0.
• CVM: Comparison x Value Mode
0 = The comparison x between the counter of the channel 0 and the comparison x value is performed when this counter is
incrementing.
1 = The comparison x between the counter of the channel 0 and the comparison x value is performed when this counter is
decrementing.

This bit is useless if the counter of the channel 0 is left aligned (CALG = 0 in
