Force-On Function
When the force-on bit is set to 1 in register foset[0] (see
Table 44), the channel is enabled regardless of the ON
pin voltage or the EN1 and EN2 bits in register chxen. In
forced-on operation, all functions operate normally with
the notable exception that the channel does not shut
down due to any fault conditions that may arise.
There is a force-on key register fokey that must be set to
0xA5 in order for the force-on function to become active
(see Table 45). If this register contains any value other
than 0xA5, writing 1 to the force-on bits in register foset
has no effect. This provides protection against acciden-
tal force-on operation that might otherwise be caused by
an erroneous I
2
C write.
Fault Logging and Indications
The device provides detailed information about any fault
conditions that have occurred. The FAULT output spe-
cifically indicates a circuit-breaker shutdown event, while
the ALERT output is asserted whenever a problem has
occurred that requires attention or interaction.

Description:
Circular buffer stop delay: any integer number between 0 and 50 samples that are to be recorded to a
buffer after a shutdown event, before the buffer stops storing new data
