Detailed Description

HAL_SMEM.

Function Documentation

hal_smem_buf_end_addr()

uint32_t hal_smem_buf_end_addr

(

void

)

Get smem end address for data buffer.

Returns

end address.

hal_smem_buf_start_addr()

uint32_t hal_smem_buf_start_addr

(

void

)

Get smem start address for data buffer.

Returns

start address.

hal_smem_init()

void hal_smem_init

(

void

)

Globally enable HW shared memory.

Note

Shared memory is used by the following HW modules:

1. BLE
2. Antena control Rx data
3. Audio Rx
4. Audio Tx
5. HWACC
6. Sensor ADC
7. AHB trigger The API is based on Inplay configuration tool generated configuration parameters for the shared memory.

Returns

void. This function has no return value.

hal_smem_pm_resume()

void hal_smem_pm_resume

(

void

)

PM restore SMEM HW configuration registers.

Returns

No return

hal_smem_pm_suspend()

void hal_smem_pm_suspend

(

void

)

PM save SMEM HW configuration registers.

Returns

No return

hal_smem_retn()

void hal_smem_retn	(	uint32_t	offset,
		uint32_t	size
	)

Enable/Disable shared memory retention.

Parameters

[in]	en	1: enable retention, 0: otherwise
[in]	offset	The retention starting offset in the shared memory
[in]	size	The retention size

Returns

void. This function has no return value.
