MOVE

Set the left register to the value of the right operand (register or literal value).

Opcode	Bytes	Cycles	Form	Example
$40	3	2	move b:_, {byte}	move b:1, 123
$41	3	2	move p:_, {s_byte}	move p:2, 123
$b2	4	2	move p:_, {pair}	move p:2, 12345
$42	3	2	move i:_, {s_byte}	move i:4, 123
$b3	4	2	move i:_, {s_pair}	move i:4, 12345
$e2	5	2	move i:_, {u_trio}	move i:4, $12_3abc
$43	3	2	move i:_, xhex {xint}	move i:4, xhex $d000_0000
$44	3	3	move b:_, b:_	move b:1, b:2
$45	3	3	move p:_, p:_	move p:2, p:4
$46	3	3	move i:_, i:_	move i:4, i:8
$26	2	2	move sp, i:_	move sp, i:4
$27	2	2	move i:_, sp	move i:4, sp
$b4	4	1	move fp, {u_trio}	move fp, $12_3abc
$14	1	1	move fp, sp	move fp, sp
$15	1	1	move sp, fp	move sp, fp

Notes

• The left operand is the target where the output will go.

• For example, move p:0, 123 puts the literal value 123 into register p:0.

• For example, move b:1, b:2 copies the value of b:2 into the register b:1.

• For example, move i:4, xhex $d000_0000 puts the value $d000_0000 into i:4. Large numbers must be compatible with XHEX encoding.

• This instruction does not affect the CPU condition flags.

Jump forms

Two forms of the jump pseudo-instruction are actually implemented as move instructions involving the ip register:

$b5	4	1	move ip, {u_trio}	jump fixed $12_3abc
$28	2	2	move ip, i:_	jump i:4
