Hello,
I have an application where there is not GPIO resources to monitor XERR but we need LED Open Detection. The plan is to periodically read out SID to see if there is an error in the SID register.
My question is what is the proper time to pulse XLAT and read out SID? When does XERR transition back from low to high - once the XLAT is pulsed and SID is read out or once the error goes away (which means they could miss it when LEDs are PWM'd)?
Regards,
Kevin
