FPE_FPCCR

Bit Field

Read/Write

Field Name

Description

31

RW

ASPEN

When this bit is set to 1, execution of a floating-point instruction sets the CONTROL.FPCA bit to 1

30

RW

LSPEN

Enable lazy contect save of FP state

29

RW

LSPENS

This bit controls whether the LSPEN bit is writable from the Non-secure state

28

RW

CLRONRET

Clear floating point caller saved register on exception return

27

RW

CLRONRETS

CLRONRET secure only

26

RW

TS

Threat FP registers as Secure enable

10

RW

UFRDY

Indicates whether the software executing when the processor allocated the floating-point stack frame was able to set the Usage Fault exeption to pending.

9

RW

SPLIMVIOL

This bit is banked between the Security states and indicates whether the floating-point context violates the stack pointer limit that was active when lazy state preservation was activated.

8

RW

MONRDY

Indicates whether the software executing when the processor allocated the floating-point stack frame was able to set the debug monitor execption to pending.

7

RW

SFRDY

Indicates whether the software executing when the processor allocated the floating-point stack frame was able to set the secure fault exception to pending.

6

RW

BRDY

Indicates whether the software executing when the processor allocated the floating-point stack frame was able to set the bus fault exception to pending.

5

RW

MMRDY

Indicates whether the software executing when the processor allocated the floating-point stack frame was able to set the Mem Manage exception to pending.

4

RW

HFRDY

Indicates whether the software executing when the processor allocated the floating-point stack frame was able to set the Hard fault exception to pending.

3

RW

THREAD

Indicates the processor mode when it allocated the floating-point stack frame.

2

RW

S

Security status of the floating-point context

1

RW

USER

Indicates the privilege level of the software executing when the processor allocated the floating-point stack frame

0

RW

LSPACT

Indicates whether lazy preservation of the floating-point state is active.
