Floating-point Math Instructions
Section 3-15
Description
MOVF(469) outputs the single-precision floating-point number (32-bit source
data in IEEE754 format) from source words S+1 and S to destination words
D+1 and D.
Flags
Precautions
When MOVF(469) is executed, the Error Flag is turned OFF.
If the source data in S+1 and S is 0, the Equals Flag is turned ON. If the
source data is non-zero, the Equals Flag is turned OFF.
If the source data in S+1 and S is negative, the Negative Flag is turned ON.
Operation Example
Indirect DM/EM
addresses in binary
@ D00000 to @ D32767
@ E00000 to @ E32767
@ En_00000 to @ En_32767
(n = 0 to C)
Indirect DM/EM
addresses in BCD
*D00000 to *D32767
*E00000 to *E32767
*En_00000 to *En_32767
(n = 0 to C)
Constants

When input condition W00000 is ON, the content of D00000 and D00001 (+
is stored in floating-point format (IEEE754 format).
