Product Number: ADSP-21489BSWZ-4B
I'm using ADSP-21489 for more than 10 years, and I started to have watchdog clock issue with resonator. The ADSP is booting up to the initialization of the watchdog counter (wait that the WDTCURCNT register is loaded) and stay frozen until the watchdog clock start (can take up to 10 minutes). Can it be related to new resonator Abracon Corporation AWSCR-2.00CPLB-C47-T4 that replace the obsolete CSTCC2M00G56-R0 (new resonant Impedance is 100 Ohm vs 80 Ohm for the original part) ?
