22.7. Flash Error Reset
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.
22.8. SmaRTClock (Real Time Clock) Reset
The SmaRTClock can generate a system reset on two events: SmaRTClock Oscillator Fail or SmaRT-
Clock Alarm. The SmaRTClock Oscillator Fail event occurs when the SmaRTClock Missing Clock Detector
is enabled and the SmaRTClock clock is below approximately 20 kHz. A SmaRTClock alarm event occurs
when the SmaRTClock Alarm is enabled and the SmaRTClock timer value matches the ALARMn regis-
ters. The SmaRTClock can be configured as a reset source by writing a 1 to the RTC0RE flag (RST-
SRC.7). The SmaRTClock reset remains functional even when the device is in the low power Suspend or
Sleep mode. The state of the RST pin is unaffected by this reset.
22.9. 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 this reset.

A Flash write or erase is attempted above user code space. This occurs when PSWE is set to 1 and a
MOVX write operation targets an address above the Lock Byte address.
A Flash read is attempted above user code space. This occurs when a MOVC operation targets an
address above the Lock Byte address.
A Program read is attempted above user code space. This occurs when user code attempts to branch
to an address above the Lock Byte address.
A Flash read, write or erase attempt is restricted due to a Flash security setting (see Section
“18.3. Security Options” on page 247).
A Flash write or erase is attempted while the V
