34.2.4.6.1 Syntax
34.2.4.6.2 Operation
34.2.4.6 LDM and STM
Load and Store Multiple registers.
op{addr_mode}{cond} Rn{!}, reglist
where:
op is one of:
addr_mode is any one of the following:
cond is an optional condition code, see
Rn is the register on which the memory addresses are based.
! is an optional writeback suffix. If ! is present the final address, that is loaded from or
stored to, is written back into Rn.
reglist is a list of one or more registers to be loaded or stored, enclosed in braces. It can
contain register ranges. It must be comma separated if it contains more than one register
or register range, see
LDM and LDMFD are synonyms for LDMIA. LDMFD refers to its use for popping data from Full
Descending stacks.
LDMEA is a synonym for LDMDB, and refers to its use for popping data from Empty Ascending
stacks.
STM and STMEA are synonyms for STMIA. STMEA refers to its use for pushing data onto Empty
Ascending stacks.
STMFD is s synonym for STMDB, and refers to its use for pushing data onto Full Descending
stacks
LDM instructions load the registers in reglist with word values from memory addresses
based on Rn.
STM instructions store the word values in the registers in reglist to memory addresses
based on Rn.
For LDM, LDMIA, LDMFD, STM, STMIA, and STMEA 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 happens in order of increasing register numbers, with
the lowest numbered register using 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.
LDM: Load Multiple registers.
STM: Store Multiple registers.
IA: Increment address After each access. This is the default.
DB: Decrement address Before each access.
