Write:
In event counting mode, PEDGE selects either the rising or falling
edge of the input at PA7 to increment the pulse accumulator counter.
In gated accumulation mode, PEDGE determines which input level at
PA7 inhibits counter increments from the internal clock.
shows the relationship between PEDGE and PAMOD.
