This bit field shows the current state of the running count as it decrements.
Software loads the fixed count bit field with the value to down count.
If the reload bit is set to one, then the new value will be loaded into the running count the next time it reaches
zero.
If the update bit is set to one, then the new value is also copied into the running count, immediately.
If both the reload and update bits are set to zero, then the new value is never picked up by the running count.
