Cy_Mpc_ConfigRotMpcStruct()

cy_en_mpc_status_t Cy_Mpc_ConfigRotMpcStruct	(	MPC_Type *	base,
		const uint32_t	addOffset,
		const uint32_t	size,
		const cy_stc_mpc_rot_cfg_t *	rotConfig
	)

Initializes the referenced mpc by setting the Protection Context (PC), NS/S and RW/R/W permissions.

This is called by ROT (Root of Trust) module.

Parameters

base	Base address of MPC being configured
addOffset	Offset in the memory from the memory start address to set permissions for
size	Size of the memory to set permissions for
rotConfig	MPC configuration structure to be used by the ROT code

Returns

Initialization status

Cy_Mpc_ConfigMpcStruct()

cy_en_mpc_status_t Cy_Mpc_ConfigMpcStruct	(	MPC_Type *	base,
		const uint32_t	addOffset,
		const uint32_t	size,
		const cy_stc_mpc_cfg_t *	config
	)

Initializes the referenced MPC by setting the NS/S permissions.

Parameters

base	Base address of MPC being configured
addOffset	Offset in the memory from the memory start address to set permissions for
size	Size of the memory to set permissions for
config	MPC configuration structure to be used

Returns

Initialization status

Cy_Mpc_GetRotBlockAttr()

cy_en_mpc_status_t Cy_Mpc_GetRotBlockAttr	(	MPC_Type *	base,
		const cy_en_mpc_prot_context_t	pc,
		const uint32_t	addOffset,
		cy_stc_mpc_rot_block_attr_t *	p_block_settings
	)

Get MPC attributes settings corresponding to block and the Protection Context (PC) for ROT (Root of Trust)

Parameters

base	Base address of MPC being configured
pc	Protection Context
addOffset	Offset in the memory from the memory start address to get attributes for
p_block_settings	Pointer to return value of block settings

Returns

Initialization status

Cy_Mpc_GetBlockAttr()

cy_en_mpc_status_t Cy_Mpc_GetBlockAttr	(	MPC_Type *	base,
		const uint32_t	addOffset,
		cy_stc_mpc_block_attr_t *	p_block_settings
	)

Get MPC attributes settings corresponding to a block.

Parameters

base	Base address of MPC being configured
addOffset	Offset in the memory from the memory start address to get attributes for
p_block_settings	Pointer to return value of block settings

Returns

Initialization status

control	Auto increment control

Cy_Mpc_SetViolationResponse()

__STATIC_INLINE cy_en_mpc_status_t Cy_Mpc_SetViolationResponse	(	MPC_Type *	base,
		const cy_en_mpc_resp_cfg_t	mpcResponse
	)

Set MPC Violation Response.
