We have a situation on one of our legacy design of 320C31 DSP. Reset pin of C31 is connecting to Maxim Power on Reset chip (MAX708). At power up, There is a clock coming in to X2_CLK of C31, but there is no divided by two H1 nor H3 clocks coming out. If we force external Master Reset to MAX708, to create C31 reset after power up, H1 clock will come out. Once the H1 clocks coming out, we ...
