Functional Description
For POL(n) = 1, POL(n+1) = 1, and deadtime enabled, a falling edge on the output of
channel (n) remains high for the duration of the deadtime delay, after which the falling
edge appears on the output. Similarly, when a rising edge is due on the output of channel
(n), the channel (n+1) output remains high for the duration of the deadtime delay, after
which the channel (n+1) output will have a falling edge.
