Special Considerations when Using Floating Point Parameters
If any of the parameters (except Output) are NAN (not a number),
Infinity, or De-normalized; then the result is -NAN.
If y
1
- y
0
or x
1
- x
0
result in an overflow, then the result is -NAN
Other Considerations
If y
1
- y
0
= 0, the Result becomes the Scaled Start value
If x
1
- x
0
= 0 and x = x
0
, the Result becomes the Scaled Start value
If x
1
- x
0
= 0 and x does not equal x
0
, The Result becomes a negative
overflow (for integer values) or a negative NAN (for floating point values)

(2) See Important note about indirect addressing.
IMPORTANT
You cannot use indirect addressing with: S, ST, MG, PD,
RTC, HSC, PTO, PWM, STI, EII, BHI, MMI, CS, IOS, and
DLS files.
IMPORTANT
Do not use the High Speed Counter Accumulator
(HSC.ACC) for the Scaled Output parameter in the SCP
instruction.
