AND is a Super FX instruction that performs a logical AND on the source register and Rn. The conjunction is stored in the destination register. The operand cannot be R0.
The ALT0 state is restored.
The source and destination registers should be specified in advance using WITH, FROM, or TO. Otherwise, R0 serves as the default.
Syntax
AND Rn AND #n
Example 1
AND R8 ; R0 AND R8 -> R0
; 163ah and 00ffh -> 003ah
FROM R9 ; set the source reg to R9
TO R10 ; set the dest reg to R10
AND R7 ; R9 AND R7 -> R10
; 55aah and ff00h -> 5500h
Example 2
Let:
R0 = 3e5dh (0011 1110 0101 1101b)
After executing AND #6h:
R0 = 0004h (0000 0000 0000 0100b)
