#define __DCACHE_PRESENT

Data Cache present or not.

#define __DSP_PRESENT

DSP extension present or not.

#define __DTCM_PRESENT

Data Tightly Coupled Memory is present or not.

#define __FPU_DP

Double precision FPU present.

The combination of the defines __FPU_PRESENT and __FPU_DP determine the whether the FPU is with single or double precision as shown in the table below.

__FPU_PRESENT __FPU_DP Description
0 ignored Processor has no FPU. The value set for __FPU_DP.
1 0 Processor with FPU with single precision.
1 1 Processor with FPU with double precision.
#define __FPU_PRESENT

FPU present or not.

The combination of the defines __FPU_PRESENT and __FPU_DP determine the whether the FPU is with single or double precision as shown in the table below.

__FPU_PRESENT __FPU_DP Description
0 ignored Processor has no FPU. The value set for __FPU_DP.
1 0 Processor with FPU with single precision.
1 1 Processor with FPU with double precision.

FPU present

The

#define __ICACHE_PRESENT

Instruction Cache present or not.

#define __MPU_PRESENT

MPU present or not.

#define __NVIC_PRIO_BITS

Number of Bits used for Priority Levels.

#define __PMU_NUM_EVENTCNT

PMU Event Counters.

The number of Event counters if PMU is present (see __PMU_PRESENT)

#define __PMU_PRESENT

PMU present or not.

#define __SAUREGION_PRESENT

SAU regions present or not.

#define __SC000_REV

SC000 Core revision r0p1.

([15:8] revision number, [7:0] patch number)

#define __SC300_REV

SC300 Core revision r0p1.

([15:8] revision number, [7:0] patch number)

#define __Vendor_SysTickConfig

Set to 1 if a venor specfic SysTick configuration is used.

If this define is set to 1, then the default SysTick_Config function is excluded. In this case, the file device.h must contain a vendor specific implementation of this function.

#define __VTOR_PRESENT

VTOR present or not.
