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.

Error Flag ER
Equals Flag =
Negative Flag N
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.
When input condition W00000 is ON, the content of D00000 and D00001 (+3.0)
MOVF
is stored in floating-point format (IEEE754 format).
