These registers contain the number of active input edges on the PAI pin
since the last reset.
Reading the pulse accumulator counter registers immediately after an
active edge on the PAI pin may miss the last count since the input first
has to be synchronized with the bus clock.
To ensure coherent reading of the PA counter, such that the counter
does not increment between back-to-back 8-bit reads, it is
recommended that only half-word (16-bit) accesses be used.
