MICROPROCESSOR INSTRUCTION REFERENCE->FMOVE

Move Floating-Point Data Register

Compatibility: ColdFire chips with a floating-point unit (FPU)

Source -> Destination

    

Assembler Syntax:	FMOVE.fmt <ea>,FPx
	FMOVE.fmt FPy,<ea>
	FADD.D FPy,FPx
	FrADD.fmt <ea>,FPx
	FrADD.D FPy,FPx

where r is rounding precision, S or D

Format: Byte (B), Word (W), Long (L), Single-precision (S), Double-precision (D)

Moves the contents of the source operand to the destination operand.

FSMOVE rounds to single-precision, FDMOVE rounds to double-precision and FMOVE rounds to the precision specified by the floating point control register FPCR (which by default is double-precision).

Floating-Point Status Register:

N	Not affected
Z	Not affected
I	Not affected
NAN	Not affected
BSUN	Always cleared
INAN	Set if the input is not-a-number; else cleared
IDE	Set if the input is a denormalised number; else cleared
OPERR	Always cleared
OVFL	Always cleared
UNFL	Always cleared
DZ	Always cleared
INEX	Set if the infinitely-precise mantissa of the intermediate result has more significant bits than can be represented exactly in the selected rounding precision; or if the input is a denormalised number and the IDE exception is disabled; else cleared
