Brown-out Reset (BOR)
On-chip Brown-out Reset circuitry places the device into reset when the device voltage falls
below a trip point (BV
side the valid operation range of the device. Brown-out resets are typically used in AC line appli-
cations or large battery applications where large loads may be switched in (such as automotive),
and cause the device voltage to temporarily fall below the specified operating minimum.
The BODEN configuration bit can disable (if clear/programmed) or enable (if set) the Brown-out
Reset circuitry. If V
