Function Documentation

void IEE_APC_GlobalEnable

(

IEE_APC_Type *

base

)

This function enables IOMUXC LPSR GPR and APC IEE for setting the region.

param base APC IEE peripheral address.

void IEE_APC_GlobalDisable

(

IEE_APC_Type *

base

)

This function disables IOMUXC LPSR GPR and APC IEE for setting the region.

param base APC IEE peripheral address.

status_t IEE_APC_SetRegionConfig	(	IEE_APC_Type *	base,
		iee_apc_region_t	region,
		uint32_t	startAddr,
		uint32_t	endAddr
	)

This function configures APC IEE Memory Region Descriptor according to region configuration structure.

Parameters

base	APC IEE peripheral address.
region	Selection of the APC IEE region to be configured.
startAddr	Start encryption adress for the selected APC IEE region.
endAddr	End encryption adress for the selected APC IEE region.

status_t IEE_APC_LockRegionConfig	(	IEE_APC_Type *	base,
		iee_apc_region_t	region,
		iee_apc_domain_t	domain
	)

This function locks writting to IOMUXC LPSR GPR and APC IEE encryption region setting registers. Only system reset can clear the LPSR GPR and APC IEE-RDC_D0/1 Lock bit

Parameters

base	APC IEE peripheral address.
region	Selection of the APC IEE region to be locked.

void IEE_APC_RegionEnable	(	IEE_APC_Type *	base,
		iee_apc_region_t	region
	)

This function enables encryption/decryption by writting to IOMUXC LPSR GPR.

Parameters

base	APC IEE peripheral address.
region	Selection of the APC IEE region to be enabled.
