MOVEW (Move Word) is a Super FX macro instruction that loads data from the Game Pak.

Syntax

MOVEW Rn, (Rn')
MOVEW (Rn'), Rn

Example 1

Let:

R3 = 6480h
(71:6480h) = 2eh
(71:6481h) = c0h
RAMBR = 71h

After executing this program:

MOVEW R5, (R3)
; (R3) -> R5 (low byte)
; (R3+1) -> R5 (high byte)

We have:

R5 = c02eh

Example 2

Let:

R6 = 0822h
(70:0822h) = 43h
(70:0823h) = 96h
RAMBR = 70h

After executing this program:

MOVEW R0, (R6)

We have:

R0 = 9643h

Example 3

Let:

R9 = bfa3h
R10 = 4444h
RAMBR = 71h

After executing this program:

MOVEW (R10), R9

We have:

(71:4444h) = a3h
(71:4445h) = bfh

Example 4

Let:

R0 = 3151h
R6 = 92a0h
RAMBR = 71h

After executing this program:

MOVEW (R6), R0

We have:

(71:92a0h) = 51h
(71:92a1h) = 31h
