Detailed Description

Busy Status Register (BSR) driver.

Function Documentation

sys_sw_bsr_acquire()

void sys_sw_bsr_acquire	(	SW_BSR_MASTER_ID	sw_bsr_master_id,
		uint32_t	periph_id
	)

Acquire exclusive access to a specific peripheral when it could also be used by another master. This function will block until access is granted.

Parameters

[in]	sw_bsr_master_id	The SW BSR ID of the relevant master
[in]	periph_id	The peripheral id for which exclusive access must be granted. Valid range is (0 - 15). Check HW_SYS_BSR_PERIPH_ID.

sys_sw_bsr_acquired()

bool sys_sw_bsr_acquired	(	SW_BSR_MASTER_ID	sw_bsr_master_id,
		uint32_t	periph_id
	)

Checks if exclusive access to a specific peripheral has been acquired from a given master.

Parameters

[in]	sw_bsr_master_id	The SW BSR ID of the relevant master
[in]	periph_id	The peripheral id for which exclusive access will be checked. Valid range is (0 - BSR_PERIPH_ID_MAX). Check HW_SYS_BSR_PERIPH_ID.

Returns

true if peripheral exclusive access has been acquired from the specific master, else false.

sys_sw_bsr_release()

void sys_sw_bsr_release	(	SW_BSR_MASTER_ID	sw_bsr_master_id,
		uint32_t	periph_id
	)

Releases the exclusive access from a specific peripheral so it can be used by another master.

Parameters

[in]	sw_bsr_master_id	The SW BSR ID of the relevant master
[in]	periph_id	The peripheral id for which exclusive access must be released. Valid range is (0 - 15). Check HW_SYS_BSR_PERIPH_ID.
