Event register sets

An event register set is made up of an event register and an event enable register
3-5). When an event occurs, the appropriate event register bit sets to 1. The bit remains
latched (to 1) until the register is reset. When an event register bit is set and its
corresponding enable bit is set (as programmed by the user), the output (summary) of the
register will set to 1, which in turn sets the summary bit of the status byte register.
