Operation and Questionable Event Registers
Event registers reflect changes in the conditions of the switch. Each bit
in the operation event register and the questionable event register is
associated with a bit in the corresponding condition register. Depending
on the values of the positive transition register and the negative
transition register, a bit in the event register can be set when the
associated bit in the condition register changes from 0 to 1, from 1 to 0,
or both. If both the positive transition and negative transition bits are
set to 0, the event register bit is not set on either transition.

Operation and Questionable Event Enable Registers
The event enable registers determine which event bits in the associated
event register causes the summary message bit in the status byte
register to be set. If any event bit in the event register is set while its
associated bit in the event enable register is also set, the summary
message bit is set to true.
