Function
MOV B/W (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.
POP W @SP+
→
Rn
Pops a 16-bit general register from the stack. Equivalent to
MOV.W @SP+, Rn.
PUSH W Rn
→
@–SP
Pushes a 16-bit general register onto the stack. Equivalent to
MOV.W Rn, @–SP.
Notes: * Size: Operand size
B: Byte
W: Word
Certain precautions are required in data access. See section 2.9.1, Notes on Data Access, for
details.
Figure 2.7 lists the format of the bit manipulation instructions.
