Description

Floating Point Context Control Register

Fields

LSPACT

Indicates whether Lazy preservation of the FP state is active.
USER

Indicates the privilege level of the software executing was User (Unpriviledged) when the processor allocated the FP stack frame.
THREAD

Indicates the processor mode was Thread when it allocated the FP stack frame.
HFRDY

Indicates whether the software executing when the processor allocated the FP stack frame was able to set the HardFault exception to pending.
MMRDY

Indicates whether the software executing when the processor allocated the FP stack frame was able to set the MemManage exception to pending.
BFRDY

Indicates whether the software executing when the processor allocated the FP stack frame was able to set the BusFault exception to pending.
MONRDY

Indicates whether the the software executing when the processor allocated the FP stack frame was able to set the DebugMonitor exception to pending.
LSPEN

Lazy State Preservation ENable. When the processor performs a context save, space on the stack is reserved for the floating point state but it is not stacked until the new context performs a floating point operation.
ASPEN

Automatic State Preservation ENable. When this bit is set is will cause bit [2] of the Special CONTROL register to be set (FPCA) on execution of a floating point instruction which results in the floating point state automatically being preserved on exception entry.
