BMU interrupts
Interrupt generation rules
•
Each interrupt source has a dedicated status bit that indicates if an interrupt has been
issued or not.
•
A status flag shall be cleared by software by writing a 1 to the corresponding bit
position.
•
If a status flag is set and a new hardware condition leading to an interrupt occurs, no
new interrupt is generated. If a software access to clear the interrupt status bit
takes place and in the same cycle the hardware wants to set the bit, the
hardware condition wins the arbitration.
