5.1.5
PIC17C7XX devices have on-chip Brown-out Reset
circuitry. This circuitry places the device into a RESET
when the device voltage falls below a trip point (BV
This ensures that the device does not continue pro-
gram execution outside the valid operation range of the
device. Brown-out Resets are typically used in AC line
applications, or large battery applications, where large
loads may be switched in (such as automotive).
The BODEN configuration bit can disable (if clear/
programmed), or enable (if set) the Brown-out Reset
circuitry. If V

greater than parameter #35, the Brown-out situation
will reset the chip. A RESET is not guaranteed to occur

Brown-out Reset. The Power-up Timer/Oscillator Start-

Brown-out situations.
In some applications, the Brown-out Reset trip point of
the device may not be at the desired level. Figure 5-8
