the lowest memory address and the highest number register using the highest memory address. If the
writeback suffix is specified, the value of Rn + 4 * (n-1) is written back to Rn.
For LDMDB, LDMEA, STMDB, and STMFD the memory addresses used for the accesses are at 4-byte
intervals ranging from Rn to Rn - 4 * (n-1), where n is the number of registers in reglist. The accesses
happen in order of decreasing register numbers, with the highest numbered register using the highest
memory address and the lowest number register using the lowest memory address. If the writeback
suffix is specified, the value of Rn - 4 * (n-1) is written back to Rn.
The PUSH and POP instructions can be expressed in this form. See Section 3.4.7 (p. 53) for details.
3.4.6.3 Restrictions
In these instructions:
Rn must not be PC
reglist must not contain SP
in any STM instruction, reglist must not contain PC
in any LDM instruction, reglist must not contain PC if it contains LR
reglist must not contain Rn if you specify the writeback suffix.
When PC is in reglist in an LDM instruction:
bit[0] of the value loaded to the PC must be 1 for correct execution, and a branch occurs to this
halfword-aligned address
if the instruction is conditional, it must be the last instruction in the IT block.
3.4.6.4 Condition flags
These instructions do not change the flags.
3.4.6.5 Examples
LDM
R8,{R0,R2,R9}
; LDMIA is a synonym for LDM
STMDB
R1!,{R3#R6,R11,R12}
3.4.6.6 Incorrect examples
STM
R5!,{R5,R4,R9} ; Value stored for R5 is unpredictable
LDM
R2, {}
; There must be at least one register in the list
3.4.7 PUSH and POP
Push registers onto, and pop registers off a full-descending stack.
3.4.7.1 Syntax
PUSH{cond} reglist
POP{cond} reglist
where:
cond
is an optional condition code, see Section 3.3.7 (p. 43) .
reglist
is a non-empty list of registers, enclosed in braces. It can contain register ranges. It must be
comma separated if it contains more than one register or register range.
