Access:
• ERSTL: External Reset Length
This field defines the external reset length. The external reset is asserted during a time of 2
allows assertion duration to be programmed between 60 μs and 2 seconds.
• KEY: Password
Should be written at value 0xA5. Writing any other value in this field aborts the write operation.
