I don't understand how to use OTW, OTWE, OTWS.
IC is high temp -> OTWS=1 -> If OTWE=1 then OTW=1 and state transition NORMAL to OVERTEMP.
IC is high temp -> OTWS=1 -> If OTWE=0 then OTW=0 and no state transition.
Is it correct ?
Could you please specify which device you are referring to?
I'm sorry that I didn't mention my device.
I'm using TJA1145.
Your understanding is correct. The TJA1145 issues a warning when the IC temperature rises above the overtemperature warning threshold (Tth(warn)otp). When this happens, status bit OTWS is set and an overtemperature interrupt is generated (OTW = 1), if enabled (OTWE = 1).
Thank you very much for your quick response.
