Deglitch
Fault conditions are detected at the end of each con-
version. If 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
outside the threshold for a certain number of acquisi-
tions as determined by the deglitch setting in r4Fh[7:6]
(see Table 25).
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 r18h and r19h in the
extended page, as shown in Table 22. Clear a fault flag
by writing a ‘1’ to the appropriate 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 23). The fault flag will only be set if the matching
enable bit in the critical fault enable register is also set.
Critical Faults
If a specific input threshold is critical to the operation of
the system, an automatic fault log can be configured to
shut down all the EN_OUT_s and trigger a transfer of
fault information to EEPROM. For a fault condition to
trigger a critical fault, set the appropriate enable bit in
registers r48h to r4Ch (see Table 23).
Logged fault information is stored in EEPROM registers
r00h to r0Eh (see Table 24). Once a fault log event
occurs, the EEPROM is locked and must be unlocked
to enable a new fault log to be stored. Write a ‘1’ to
r5Dh[1] to unlock the EEPROM. Fault information can
be configured to store ADC conversion results and/or
fault flags in registers r01h and r02h. Select the critical
fault configuration in r47h[1:0]. Set r47h[1:0] to ‘11’ to
turn off the fault logger. All stored ADC results are 8
bits wide.
