SC32442B RISC MICROPROCESSOR
ARM INSTRUCTION SET

ASSEMBLER SYNTAX
<LDC|STC>{cond}{L} p#,cd,<Address>
LDC
Load from memory to coprocessor
STC
Store from coprocessor to memory
{L}
When present perform long transfer (N=1), otherwise perform short transfer (N=0)
{cond}
Two character condition mnemonic. See Table 3-2..
p#
The unique number of the required coprocessor
cd
An expression evaluating to a valid coprocessor register number that is placed in the
CRd
field
<Address>
can
be:
1
An expression which generates an address:
The assembler will attempt to generate an instruction using the PC as a base and a
corrected immediate offset to address the location given by evaluating the expression.
This will be a PC relative, pre-indexed address. If the address is out of range, an error
will
be
generated
2
A pre-indexed addressing specification:
[Rn]
offset
of
zero
[Rn,<#expression>]{!}
offset of <expression> bytes
3
A post-indexed addressing specification:
[Rn],<#expression
offset of <expression> bytes
{!}
write
back
the
base
register (set the W bit) if! is present
Rn
is an expression evaluating to a valid
ARM920T
register
number.
NOTES
If Rn is R15, the assembler will subtract 8 from the offset value to allow for ARM920T pipelining.
EXAMPLES
LDC
p1,c2,table
; Load c2 of coproc 1 from address
; table, using a PC relative address.
STCEQL
p2,c3,[R5,#24]!
; Conditionally store c3 of coproc 2
; into an address 24 bytes up from R5,
; write this address back to R5, and use
; long transfer option (probably to store multiple words).
NOTES
Although the address offset is expressed in bytes, the instruction offset field is in words. The assembler
will adjust the offset appropriately.
