Hello Support,

I understand when does ESM Group 2 Bit 3 occurs according to

https://e2e.ti.com/support/microcontrollers/hercules/f/312/t/592638

Question is under what condition does ESM Group 1 Bit 52 occurs?

CPU Interconnect Subsystem - Global error Group1 52

Some details similar to previous link mentioned above from experts will help me understand better.

Thank you.

Regards

The CPU Interconnect subsystem is described in section 4.3 of the Technical Reference Manual. This ESM flag will be set on a parity error in the control or address signals. The most common occurrence of ESM error Group 1 Channel 52 is an inadvertent error that may happen after running the CPU self test at a GCLK frequency greater than the maximum HCLK frequency. This behavior is explained in device erratum DEVICE#48 in the errata document. In that case, the ESM flag may be cleared and the error ignored.
