Hello,
Please answer following questions when send WR_CAN_STBY with CANWU=1 and resisters are not initialized at the restart of STANDBY state.
I use VSOUT1 so VSOUT1 is enabled while ACTIVE state.
Q1:
Is it required to disable VSOUT1 before send WR_CAN_STBY?
I’m afraid that VSOUT1 is enabled while ABIST in RESET and DIAGNOSTICS and it cause ABIST failure or any problem.
Q2:
I tested the behavior of Device STATUS after WR_CAN_STBY using EVM and result is attached file.
1) When VSOUT1=0 or VSOUT1=1 and no additional load to VSOUT1, Device Status of GUI changed Safe -> Diagnostics -> safe after WR_CAN_STBY.
2) When VSOUT1=1 and added 100hmm + 100uF load to VSOUT1 to delay the startup of VSOU1, Device Status of GUI changed Safe -> safe after WR_CAN_STBY and it seems that Diagnostics timeout counter is not working and changed from Diagnostics to Safe immediately.
Please explain the mechanism of 2)
Best Regards.
