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.
