Auto Take
Sticky Request for Single Semaphore.
Bit | Field | Type | Reset | Description |
---|---|---|---|---|
31-3 | RESERVED | R | 0h | Reserved |
2-0 | SMPH_ID | R/W | 0h | Write the semaphore ID,0x0-0x7, to SMPH_ID to request this semaphore until it is granted. When semaphore SMPH_ID is granted, event AUX_EVCTL:EVSTAT3.AUX_SMPH_AUTOTAKE_DONE becomes 1. The event becomes 0 when software releases the semaphore or writes a new value to SMPH_ID. To avoid corrupted semaphores: - Usage of this functionality must be restricted to one CPU core. - Software must wait until AUX_EVCTL:EVSTAT3.AUX_SMPH_AUTOTAKE_DONE is 1 before it writes a new value to SMPH_ID. |
