PIC16C781/782

The PLVD indicates a low voltage condition by setting
the LVDIF bit in the PIR1 register. Once set by the
PLVD module, the LVDIF bit will remain set until
cleared by software. For proper indication of a low volt-
age condition, the user should clear this bit prior to
testing.
To test for a low voltage condition, the PLVD module
compares the divided output of V
bandgap reference. The PLVD module automatically

enables this reference whenever it is enabled and pro-
vides a stability bit, BGST, to indicate when it has sta-
bilized. The bandgap reference is also enabled by
other modules within the PIC16C781/782 as part of
their operation. Other modules using the bandgap
include the following:

• BOR module
• OPA calibration module
