9.7.
If a Flash read/write/erase or program read targets an illegal address, a system reset is generated. This
may occur due to any of the following:
•
•
•
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’ fol-
lowing a software forced reset. The state of the RST pin is unaffected by this reset.

Minimum RST Low Time to
Generate a System Reset
A Flash write or erase is attempted above user code space. This occurs when PSWE is set to ‘1’ and a
MOVX operation is attempted above the user code space address limit.
A Flash read is attempted above user code space. This occurs when a MOVC operation is attempted
above the user code space address limit.
A Program read is attempted above user code space. This occurs when user code attempts to branch
to an address above the user code space address limit.
