Boot ROM health and booting status is written to a 32-bit address in M0RAM. This status is cleared on a POR or XRS reset. The previous status is retained on any other reset. For example, you should clear the status before performing a debugger device reset in order to view the latest boot ROM actions reflected in the status.
