Macro Definition Documentation

__CA_CMSIS_VERSION

#define __CA_CMSIS_VERSION

Contains the CMSIS version.

The CMSIS version is a combination of the __CA_CMSIS_VERSION_MAIN (bits 31..16) and __CA_CMSIS_VERSION_SUB (bits 15..0).

Code Example:

#if defined(__CA_CMSIS_VERSION) && \
    (__CA_CMSIS_VERSION >= 0x00060000)
#error Yes, we have CMSIS 6.0 or later
#else
#error We need CMSIS 6.0 or later!
#endif

__CA_CMSIS_VERSION_MAIN

#define __CA_CMSIS_VERSION_MAIN

Contains the CMSIS major version.

The CMSIS major version can be used to differentiate between CMSIS major releases.

__CA_CMSIS_VERSION_SUB

#define __CA_CMSIS_VERSION_SUB

Contains the CMSIS minor version.

The CMSIS minor version can be used to query a CMSIS release update level.

__CA_REV

#define __CA_REV   0x0000

Contains the core revision for a Cortex-A class device.

Use this define to query the core design revision number implemented in the selected device.

Bits	Name	Function
[15:8]	REV	Revision number
[7:0]	PATCH	Patch number

Example:

#if __CA_REV < 0x0201
#error This code needs at least a core revision r2p1.
#endif

__CORTEX_A

#define __CORTEX_A   0x0000

Contains the core family for a Cortex-A class device.

Use this define to query the actual Cortex-A class device number implemented in the selected device.

Example:

#if __CORTEX_A == 5
#warning Running on Cortex-A5.
#elif __CORTEX_A == 7
#warning Running on Cortex-A7.
#elif __CORTEX_A == 9
#warning Running on Cortex-A9.
#endif
