Involuntary EQU trigger
#1
Hi all!

I would like to ask why EQU toggle when ServoCapt cross zero.

My suspect is that the compare registers are not dealing well with two's complement when the register becomes positive (example: 111111..... to 000000...)

When I use CompA and CompB on positive or negative domain strictly, it works as expected.

Maybe its related to Choi Woo Shik question (http://forums.deltatau.com/showthread.php?tid=3089)

Firmware: 2.5.4.0
IDE version: 4.3.2.19

Thanks!
George
