Function
(EAs) → Rd, Rs → (EAd)
Moves data between two general registers or between a general
register and memory, or moves immediate data to a general
register.
The Rn, @Rn, @(d:16, Rn), @aa:16, #xx:16, @–Rn, and @Rn+
addressing modes are available for word data. The @aa:8
addressing mode is available for byte data only.
The @–R7 and @R7+ modes require word operands. Do not
specify byte size for these two modes.
@SP+ → Rn
Pops a 16-bit general register from the stack. Equivalent to
MOV.W @SP+, Rn.
Rn → @–SP
Pushes a 16-bit general register onto the stack. Equivalent to
MOV.W Rn, @–SP.
