(1) instructions (Mnemonics and Operands)
An instruction to the S1C17 Core is generally composed of <Mnemonic> + <Operand> . Some instructions do
not contain an operand.
general notation forms of instructions
General forms: <Mnemonic>
<Mnemonic> tab or space <Operand>
<Mnemonic> tab or space <Operand 1>
,
<Operand 2>
Examples:
nop
call SUB1
ld %r0,0x4
There is no restriction as to where the description of a mnemonic may begin in a line. A tab or space
preceding a mnemonic is ignored. Generally, mnemonics are justified left by tab setting.
An instruction containing an operand needs to be broken with one or more tabs or spaces between the
mnemonic and the operand. If there are plural operands, the operands are separated from each other with
one comma (,). Space between operands is ignored.
The elements of operands will be described further below.
Types of mnemonics
The following S1C17 Core instructions can be used in the S1C17 Family:
ld.b ld.ub ld ld.a
add add/c add/nc add.a add.a/c add.a/nc
adc adc/c adc/nc sub sub/c sub/nc
sub.a sub.a/c sub.a/nc sbc sbc/c sbc/nc
cmp cmp/c cmp/nc cmp.a cmp.a/c cmp.a/nc
cmc cmc/c cmc/nc
and and/c and/nc or or/c or/nc
xor xor/c xor/nc not not/c not/nc
sr sa sl swap
cv.ab cv.as cv.al cv.la cv.ls
jpr jpr.d jpa ipa.d jrgt jrgt.d
jrge jrge.d jrlt jrlt.d jrle jrle.d
jrugt jrugt.d jruge jruge.d jrult jrult.d
jrule jrule.d jreq jreq.d jrne jrne.d
call call.d calla calla.d ret ret.d
int intl reti reti.d brk retd
ext nop halt slp ei di
ld.cw ld.ca ld.cf
Refer to the "S1C17 Core Manual" for details of each instruction.
restrictions on characters
Mnemonics can be written in uppercase (A–Z) characters, lowercase (a–z) characters, or both. For example,
"
ld
", "
LD
", and "
Ld
" are all accepted as "
ld
" instructions.
For purposes of discrimination from symbols, this manual uses lowercase characters.
More will be said about operands later.
