12-Channel/8-Channel, Flash-Configurable System
Managers with Nonvolatile Fault Registers
The general-purpose inputs/outputs (GPIO1 to GPIO8)
can be configured as ANY_FAULT outputs or dedicated
Fault1 and Fault2 outputs to indicate fault conditions.
These fault outputs are not masked by the critical fault
enable bits shown in Table 14. See the General-Purpose
Inputs/Outputs section for more information on configur-
ing GPIO_s as fault outputs.
Deglitch
Fault conditions are detected at the end of each conver-
sion. When the voltage on an input falls outside a moni-
tored threshold for one acquisition, the input multiplexer
remains on that channel and performs several succes-
sive conversions. To trigger a fault, the input must stay
Table 12. Deglitch Configuration
outside the threshold for a certain number of acquisitions
as determined by the deglitch setting in r73h[6:5] and
r74h[6:5] (see Table 12).
Fault Flags
Fault flags indicate the fault status of a particular input.
The fault flag of any monitored input in the device can be
read at any time from registers r1Bh and r1Ch, as shown
in Table 13. Clear a fault flag by writing a ‘1’ to the appro-
priate bit in the flag register. Unlike the fault signals sent
to the fault outputs, these bits are masked by the Critical
Fault Enable bits (see Table 14). The fault flag is only set
when the matching enable bit in the critical fault enable
register is also set.
