[ Operation ]

dest src

• This instruction transfers

src

dest

• If

dest

is an A0 or A1 when the size specifier (.size) you selected is (.B),

src

is zero-expanded to

transfer data in 16 bits. If

src

is an A0 or A1, data is transferred from the 8 low-order bits of A0 or A1.

[ Flag Change ]

UIOBSZDC

Conditions

S : The flag is set when the transfer resulted in MSB of

dest

= 1; otherwise cleared.

Z : The flag is set when the transfer resulted in 0; otherwise cleared.

Flag

Change

*1 If you specify (.B) for the size specifier (.size), you cannot choose A0 or A1 for

src

and

dest

simulta-

neously.

*2 If

src

is #IMM, you cannot choose dsp:8 [SP] for

dest

*3 Operation is performed on the stack pointer indicated by the U flag. You cannot choose dsp:8 [SP] for

src

and

dest

simultaneously.
