| 2:0 | SMPH_ID | Requesting a certain semaphore is done by writing the corresponding semaphore ID, 0x0-0x7, to SMPH_ID. The request is sticky and once the semaphore becomes available it will be taken. At the same time, SMPH_AUTOTAKE_DONE event is asserted. This event is deasserted when SW releases the semaphore or a new ID is written to SMPH_ID. Note: SW must wait until SMPH_AUTOTAKE_DONE event is triggered before writing a new ID to SMPH_ID . Failing to do so might lead to permanently lost semaphores as the owners may be unknown |
