The Channel Status register (CHSTATUS)
shows the status of the channels when using a synchronous or resynchronized path. There are
two different status bits in CHSTATUS for each of the available channels:
- The CHSTATUSn.BUSYCH bit will be set
when an event on the corresponding channel n has not been handled by all event users
connected to that channel.
- The CHSTATUSn.RDYUSR bit will be set
when all event users connected to the corresponding channel are ready to handle incoming
events on that channel.
