MOVE.F
MOVE.F
Move Fractional Word
MOVE.F
to/from Memory (AGU)
Description
These operations read a fractional word from memory into the high portion of a destination data register
Db, sign-extended and zero-filled.
This instruction also moves data from a register to memory without saturation. However, moving
fractional data from register to memory is generally done with saturation. These instructions are described
in MOVES.F.
The address of the access must be word-aligned.

MOVE.F #s16,Db
Loads a 16-bit immediate fractional value into a data register.
MOVE.F (a16),Db
Reads a fractional word from a 16-bit unsigned absolute address into a data register.
MOVE.F (a32),Db
Reads a fractional word from a 32-bit absolute address into a data register.
MOVE.F (EA),Db
Reads a fractional word from memory into a data register. The effective memory address is obtained from
an address register with an optional offset or post-increment.
MOVE.F (Rn+s15),Db
Reads a fractional word from memory into a data register. The effective memory address is obtained from
an address register with a signed 15-bit offset.
