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.
