Bit 0 – BERR AHB Bus Error Detection

The flag is set when an AHB bus error is detected. The flag is cleared by writing a 1 to the corresponding bit field. Writing a 0 has no effect. A hard reset will clear the register. When the bit is set, the Error non-maskable interrupt is generated.
ValueDescription
0No bus error detection.
1Bus error detection.
