CPSeffect iflags
where:
effect
is one of:
IE
Clears the special purpose register.
ID
Sets the special purpose register.
iflags
is a sequence of one or more flags:
i
Set or clear PRIMASK.
f
Set or clear FAULTMASK.
3.10.2.2 Operation
CPS
changes the PRIMASK and FAULTMASK special register values. See Section 2.1.3.6 (p. 11) for
more information about these registers.
3.10.2.3 Restrictions
The restrictions are:
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.
3.10.2.4 Condition flags
This instruction does not change the condition flags.
3.10.2.5 Examples
CPSID i
; Disable interrupts and configurable fault handlers (set PRIMASK)
CPSID f
; Disable interrupts and all fault handlers (set FAULTMASK)
CPSIE i
; Enable interrupts and configurable fault handlers (clear PRIMASK)
CPSIE f
; Enable interrupts and fault handlers (clear FAULTMASK)
3.10.3 DMB
Data Memory Barrier.
3.10.3.1 Syntax
DMB{cond}
where:
cond
is an optional condition code, see Section 3.3.7 (p. 43) .
3.10.3.2 Operation
DMB
acts as a data memory barrier. It ensures that all explicit memory accesses that appear, in program
order, before the DMB instruction are completed before any explicit memory accesses that appear, in
program order, after the DMB instruction. DMB does not affect the ordering or execution of instructions
that do not access memory.
3.10.3.3 Condition flags
This instruction does not change the flags.
