Cy_Ms_Ctl_ConfigBusMaster()

cy_en_ms_ctl_status_t Cy_Ms_Ctl_ConfigBusMaster	(	en_ms_ctl_master_t	busMaster,
		bool	privileged,
		bool	nonSecure,
		uint32_t	pcMask
	)

Configures the referenced bus master by setting the privilege , non-secure and PC mask settings.

Parameters

busMaster	Bus master being initialized
privileged	privileged setting
pcMask	pcMask
nonSecure	Bus master security setting

Returns

Initialization status

Cy_Ms_Ctl_ConfigMscAcgResp()

cy_en_ms_ctl_status_t Cy_Ms_Ctl_ConfigMscAcgResp	(	en_ms_ctl_master_sc_acg_t	busMaster,
		cy_en_ms_ctl_cfg_gate_resp_t	gateResp,
		cy_en_ms_ctl_sec_resp_t	secResp
	)

Response configuration for ACG and MSC for the referenced bus master.

Parameters

busMaster	Bus master for which response is being initialized
gateResp	Response type when the ACG is blocking the incoming transfers:
secResp	Bust master privileged setting

Returns

Initialization status

Cy_Ms_Ctl_SetActivePC()

cy_en_ms_ctl_status_t Cy_Ms_Ctl_SetActivePC	(	en_ms_ctl_master_t	busMaster,
		uint32_t	pc
	)

Set active protection context (PC)for the referenced bus master.

Parameters

busMaster	Bus master being initialized
pc	PC value

Returns

Initialization status

Cy_Ms_Ctl_GetActivePC()

uint32_t Cy_Ms_Ctl_GetActivePC

(

en_ms_ctl_master_t

busMaster

)

Reads the active protection context (PC) for the referenced bus master.

Parameters

busMaster

Bus master for which the PC value is being read

Returns

PC value

Cy_Ms_Ctl_SetSavedPC()

cy_en_ms_ctl_status_t Cy_Ms_Ctl_SetSavedPC	(	en_ms_ctl_master_t	busMaster,
		uint32_t	savedPc
	)

Set saved protection context (PC) for the referenced bus master.

Parameters

busMaster	Bus master being initialized
savedPc	PC value

Returns

Initialization status

Cy_Ms_Ctl_GetSavedPC()

uint32_t Cy_Ms_Ctl_GetSavedPC

(

en_ms_ctl_master_t

busMaster

)

Reads the saved protection context (PC) for the referenced bus master.

Parameters

busMaster

Bus master for which the saved PC value is being read

Returns

PC value

Cy_Ms_Ctl_SetPcHandler()

cy_en_ms_ctl_status_t Cy_Ms_Ctl_SetPcHandler	(	uint32_t	pc,
		cy_israddress	handler
	)

Sets the handler address for the given PC.

This is used to detect entry to Cypress "trusted" code through an exception/interrupt.

Note

The function can't update the handler address for the PC lower than the current application's PC. For example, if the application is running in PC2 it can't update handler address for PC0 or PC1.

Parameters

pc	Protection context for which the handler is being set
handler	Address of the protection context handler

Returns

Initialization status

Cy_Ms_Ctl_GetPcHandler()

cy_israddress Cy_Ms_Ctl_GetPcHandler

(

uint32_t

pc

)

Reads the handler address for the given PC.

Parameters

pc	Protection context for which the handler is being read

Returns

Address of the protection context handler
