Hardware-specific configuration attributes.
SHA2CC26X2 hardware attributes are used in the board file by the SHA2_Config struct.
| uint8_t SHA2CC26X2_HWAttrs::intPriority |
Hardware interrupt priority of the Hash accelerator.
The CC26XX provides 8 interrupt priority levels encoded in three bits:
| Value | Description |
|---|---|
| (~0) | Special value: always lowest priority across all OS kernels. |
| (7 << 5) | Priority level 7: lowest, but rather use ~0 instead. |
| .. | .. |
| (0 << 5) | Priority level 0: highest, not supported by this driver |
Hardware interrupts with priority level 0 ignore the hardware interrupt dispatcher for minimum latency. This is not supported by this driver.
