Examples
; Disable interrupts and configurable fault handlers (set PRIMASK)
; Disable interrupts and all fault handlers (set FAULTMASK)
; Enable interrupts and configurable fault handlers (clear PRIMASK)
; Enable interrupts and fault handlers (clear FAULTMASK)

CPS changes the PRIMASK and FAULTMASK special register values. See
registers” on page 48
The restrictions are:
This instruction does not change the condition flags.
• use CPS only from privileged software, it has no effect if used in unprivileged software
• CPS cannot be conditional and so must not be used inside an IT block.
