How to avoid DIV32 command?

[Darrel Taylor]

..I've problems with the DIV32 command, because it apparently disturbs DT Instant Interrupts (if you're here Darrel, can you tell me if the DIV32 command has really an impact on your interrupts?).

DIV32 does not disturb DT_INTS, and DT_INTS does not disturb DIV32.

However, DIV32 takes a while to execute, and even longer when you do a multiply before hand to load the registers with a big value.
Trying to use them inside a high frequency interrupt is unlikely to work.

Division with LONGs or N-Bit math is no better. Divisions take a long time in software.

I would go for a Huge lookup table or loaded EEPROM: those only take few uSec to be processed.

I havent problems anymore, look at the end of "Unstable sine PWM output" thread.
