Bits
Name
Function
On exception entry, the processor uses bit[9] of the stacked PSR to indicate the
stack alignment. On return from the exception it uses this stacked bit to restore the
correct stack alignment.
[8]
BFHFNMIGN
Enables handlers with priority -1 or -2 to ignore data bus faults caused by load and
store instructions. This applies to the hard fault, NMI, and FAULTMASK escalated
handlers:
0 = data bus faults caused by load and store instructions cause a lock-up
1 = handlers running at priority -1 and -2 ignore data bus faults caused by load and
store instructions.
Set this bit to 1 only when the handler and its data are in absolutely safe memory.
The normal use of this bit is to probe system devices and bridges to detect control
path problems and fix them.
[7:5]
-
Reserved.
[4]
DIV_0_TRP
Enables faulting or halting when the processor executes an SDIV or UDIV
instruction with a divisor of 0:
0 = do not trap divide by 0
1 = trap divide by 0.
When this bit is set to 0,a divide by zero returns a quotient of 0.
[3]
UNALIGN_TRP
Enables unaligned access traps:
0 = do not trap unaligned halfword and word accesses1 = trap unaligned halfword
and word accesses.
If this bit is set to 1, an unaligned access generates a usage fault.
Unaligned LDM, STM, LDRD, and STRD instructions always fault irrespective of
whether UNALIGN_TRP is set to 1.
[2]
-
Reserved.
[1]
USERSETMPEND
Enables unprivileged software access to the STIR, see Section 4.2.8 (p. 93) :
0 = disable1 = enable.
[0]
NONEBASETHRDENA
Indicates how the processor enters Thread mode:
0 = processor can enter Thread mode only when no exception is active.
1 = processor can enter Thread mode from any level under the control of an
EXC_RETURN value, see Section 2.3.7.2 (p. 27) .
4.3.9 System Handler Priority Registers
The SHPR1-SHPR3 registers set the priority level, 0 to 7 of the exception handlers that have configurable
priority.
SHPR1-SHPR3 are byte accessible. See the register summary in Table 4.12 (p. 94) for their
attributes.
The system fault handlers and the priority field and register for each handler are:
