10.7. OTP Error Reset
If an OTP program read or a write procedure targets an illegal address, a system reset is generated. This
may occur due to any of the following:
•
•
•
The OTPERR bit (RSTSRC.6) is set following any OTP error reset. The state of the RST pin is unaffected
by an OTP error reset.
10.8. Software Reset
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 a software reset.

An OTP read from firmware 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.
