Assembly implementation of the data integrity mechanism.

Macro Definition Documentation

MCUX_CSSL_DI_ASM_BASE

#define MCUX_CSSL_DI_ASM_BASE

DI SFR base address for SCM hardware.

MCUX_CSSL_DI_ASM_INIT_BASE

#define MCUX_CSSL_DI_ASM_INIT_BASE

Assembly macro: Initialize the base address for the data integrity.

This should be performed before calling other assembly macros MCUX_CSSL_DI_ASM_RECORD and MCUX_CSSL_DI_ASM_EXPUNGE. Usage in assembly: "MCUX_CSSL_DI_ASM_INIT_BASE baseReg"

Parameters

baseReg

Register that will be assigned the base address.

MCUX_CSSL_DI_ASM_INIT_BASE_COND

#define MCUX_CSSL_DI_ASM_INIT_BASE_COND

Assembly macro: conditionally initialize the base address for the data integrity.

This macro assumes the register (baseReg) contains the base address of the other HW SFR, hi(addressOtherHw). If the base addresses (DI and the other hardware) are different, this macro will initialize the base address for DI; otherwise, this macro does nothing. Using this macro can avoid initializing register with the same base address. Usage in assembly: "MCUX_CSSL_DI_ASM_INIT_BASE_COND baseReg, addressOtherHw"

Parameters

baseReg	Register that will be assigned the base address.
addressOtherHw	a constant, which is an address of another hardware SFR

MCUX_CSSL_DI_ASM_VALUE

#define MCUX_CSSL_DI_ASM_VALUE

Assembly macro: Retrieves the current data integrity value.

Usage in assembly: "MCUX_CSSL_DI_ASM_VALUE baseReg, valueReg"

Parameters

baseReg	Register that contains the base address for DI, previously initialized with MCUX_CSSL_DI_ASM_INIT_BASE.
valueReg	Register to store the DI value.

MCUX_CSSL_DI_ASM_REF_VALUE

#define MCUX_CSSL_DI_ASM_REF_VALUE

Assembly macro: Retrieves the current data integrity reference value.

Usage in assembly: "MCUX_CSSL_DI_ASM_REF_VALUE baseReg, valueReg"

Parameters

baseReg	Register that contains the base address for DI, previously initialized with MCUX_CSSL_DI_ASM_INIT_BASE.
valueReg	Register to store the reference DI value.

MCUX_CSSL_DI_ASM_WRITE_REF

#define MCUX_CSSL_DI_ASM_WRITE_REF

Assembly macro: Writes the data integrity reference value.

Usage in assembly: "MCUX_CSSL_DI_ASM_WRITE_REF baseReg, valueReg"

Parameters

baseReg	Register that contains the base address for DI, previously initialized with MCUX_CSSL_DI_ASM_INIT_BASE.
valueReg	Register that contains the reference DI value.

MCUX_CSSL_DI_ASM_RECORD

#define MCUX_CSSL_DI_ASM_RECORD

Assembly macro: Record the value for data integrity checking.

Usage in assembly: "MCUX_CSSL_DI_ASM_RECORD baseReg, valueReg"

Parameters

baseReg	Register that contains the base address for DI, previously initialized with MCUX_CSSL_DI_ASM_INIT_BASE.
valueReg	Register that contains the value which needs to be recorded.
