The FERROR bit (RSTSRC.6) is set following a FLASH error reset. The state of the /RST pin is unaffected by this
reset.
9.8.
Software may force a reset by writing a ‘1’ to the SWRSF bit (RSTSRC.4). The SWRSF bit will read ‘1’ following a
software forced reset. The state of the /RST pin is unaffected by this reset.
