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:

Opcode	Bytes	Cycles	Raw form	Jump example
$B5	4	1	MOVE IP, {U_TRIO}	JUMP FIXED $12_3ABC
$28	2	2	MOVE IP, I:_	JUMP I:4
