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:8 or #xx:16, @–Rn, and
@Rn+ addressing modes are available for byte or 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.
Rs → (EAd)
Transfers data from a general register to memory in synchronization
with the E clock.
(EAs) → Rd
Transfers data from memory to a general register in synchronization
with the E clock.
Rn → @–SP
Pushes a 16-bit general register onto the stack. Equivalent to MOV.W
Rn, @–SP.
@SP+ → Rn
Pops a 16-bit general register from the stack. Equivalent to MOV.W
@SP+, Rn.
