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. |
