2. Module: Brown-out Reset (BOR)
The BOR module may reset above the parameter
D005 value specified in Section 27.1 DC
Characteristics: Supply Voltage when:
•BORV<1:0> = 01 or 00
•FOSC is above 26 MHz
The updated BOR voltage specifications are
shown.
Work around
To address this situation:
• Reduce F
OSC to 25 MHz
• Use the lower of the two affected BOR voltage
thesholds, BORV<1:0> (CONFIG2L<4:3>) = 01
This will ensure detection of V
DD below 5.0V.
