Hello This is Park, Byung-Woo from SL company in Korea.
I have a question about COP watchdog timeout rate
I use 16MHz XTAL, and I set CMPUCOP.CR register = 0x03.
According to table7-12.COP watchdog rats. I can caculate COP watchdog timeout time is 163.84 ms (1/16MHz * 2^18)
I test watchdog timeout time using reset pin on MCU with Oscilloscope ,
The watchdog timeout time is 149.4 ms The difference is more than 10ms.
Can I know the reason? Thanks in advance.
