HWA_OpenConfig Struct Reference

Detailed Description

HWA configuration structure, which describes the configuration information, needed for hwa handle open.

Data Fields
HWA_InterruptPriority	interruptPriority
	structure holds the HWA interrupt priorities. This structure is applicable for processors that support a hardware priority, e.g R5F. In HWA, even though the four interrupts can not be generated at the same time, during the ISR execution of a HWA interrupt say L, if another HWA interrupt event H happens of a higher priority because of HWA progressing in its execution flow during this time, then the L's ISR will be preempted by H's ISR and the corresponding user provided call back function of L can therefore also get preempted by H's ISR or H's callback. User needs to keep this in mind in the design and implementation of the call back functions that were intended to benefit from such prioritization. In most use cases, it is not expected that such prioritization will be beneficial and so it is recommended to leave these settings to the default state of same priority level for all HWA interrupts.
