Note:
8.1
When employing any one of the low-power
oscillators (ECL mode, LP mode, LFINTOSC or
Timer1 Oscillator) at temperatures of -20°C or
colder, while at the same time the source voltage
supplied to the V
device may experience a Power-on Reset (POR).
Also, when the source voltage supplied to the V
pin is below 2.4 volts, at temperatures of -20°C or
colder, and a SLEEP instruction is executed, the
device may experience a Power-on Reset (POR)
upon entering Sleep mode, regardless of the type
of clock source being used or which power-
managed mode is being employed.
Work around
There are four work arounds available to avoid this
Reset condition:
Enabling the Brown-out Reset (BOR) circuitry.
Enabling the Fixed Voltage Reference (FVR)
module.
Maintaining a source voltage (V
above 2.4 volts when operating at temperatures
of -20°C or colder.
Use the LF product version (PIC18LF14K22/
13K22) where the operational V
is between 1.8V and 3.6V.
