14-188 2470-901-01 Rev. A / May 2019
When a mapped event is programmed to clear bits, the bit in the condition register is set to 0 when
the event is detected.
If the event is set to zero (0), the bit is never set.
See Event numbers (on page B-9
) for information about event numbers.
Example
status.questionable.setmap(0, 4917, 4918)
When event 4917 (the buffer is 0% filled) occurs, bit 0 is set in the condition register and the event register of
the Questionable Event Register. When event 4918 (buffer is 100% filled) occurs, bit 0 in the condition register
is cleared.
