5.3.7.11 RESETREAS
Address offset: 0x400
Reset reason
Unless cleared, the RESETREAS register will be cumulative. A field is cleared by writing '1' to it. If none
of the reset sources are flagged, this indicates that the chip was reset from the on-chip reset generator,
which will indicate a power-on-reset or a brownout reset.
