MOVES.F
Move Fractional Word to
MOVES.F
Memory With Scaling and Saturation (AGU)
Description
This operation moves a fractional word from a data register to memory. The data is scaled according to the
scaling mode and is saturated if the Ln bit is set. The address register values must be word-aligned. This
instruction is affected by by SM (Saturation Mode bit - SR[2]). When SM is set, scaling is not performed,
and the scale bits S[1:10] have no effect. The address of the access must be word-aligned.

MOVES.F Db,(a16)
Writes the HP of a data register (Db) to an absolute 16-bit memory address.
MOVES.F Db,(a32)
Writes the HP of a data register (Db) to an absolute 32-bit memory address.
MOVES.F Db,(Rn+s15)
Writes the HP of a data register (Db) to a memory address pointed to by an address register (Rn) with a
signed 15-bit offset.
MOVES.F Db,(EA)
Writes the HP of a data register (Db) to a memory address pointed to by an address register (EA) with an
optional offset or post-increment.
MOVES.F Db,(SP+s15)
Writes the HP of a data register (Db) to a memory address pointed to by the active stack pointer (SP) with
a signed 15-bit offset.
