1.6.1 Low-Power Sleep Mode Does Not Operate at 3.1V < VDD < 3.3V in PIC18F25/26K83 Devices
PIC18F25/26K83 devices reset when waking up from Sleep
while in Low-Power mode (VREGPM = 1 in the VREGCON
register) at 3.1V < VDD < 3.3V.
Work around
Method 1:
If wake-up from Sleep is needed at 3.1V < VDD < 3.3V, operate the
device in Normal Power mode (VREGPM = 0).
Method 2:
If wake-up from Sleep is needed at 3.1V < VDD < 3.3V, enable the Fixed
Voltage Reference (EN = 1 in the FVRCON register). This method
increases the current in Sleep mode by typically 7 μA.
