This issue pertains to the PIC16F1933 product
only. The PIC16LF1933 product is not affected by
this issue in any way.
When employing any one of the low-power
oscillators, (ECL mode, LP Mode, LFINTOSC, or
Timer1 Oscillator) while, at the same time, the
source voltage supplied to the V
below 2.7 volts, the device will experience a
Power-on Reset (POR).
Also, when the source voltage supplied to the V
pin is below 2.7 volts and a SLEEP instruction is
executed, the device will experience a Power-on
Reset
regardless of the type of clock source being used
or
employed.
Work around
There are three separate work-arounds available
to avoid this Reset condition. Employing any one
of these work-arounds will avoid this Reset
condition.

only to PIC16F1933.
