Table
If a GPIO_ is configured as an open-drain EXTFAULT
input/output, and EXTFAULT is pulled low by an external
circuit, bit r1Ch[5] is set.
The SMB Alert bit is set if the MAX16070/MAX16071
have asserted the SMBus Alert output. Clear by writing a
‘1’. See SMBALERT section for more details.
During normal operation, a fault condition can be con-
figured to store fault information in the flash memory by
setting the appropriate critical fault enable bits. Set the
appropriate critical fault enable bits in registers r6Eh to r72h
(see Table 14) for a fault condition to trigger a critical fault.

Critical Faults
Logged fault information is stored in flash registers r200h
to r20Fh (see Table 15). After fault information is logged,
the flash is locked and must be unlocked to enable a
new fault log to be stored. Write a ‘0’ to r8Ch[1] to unlock
the fault flash. Fault information can be configured to
store ADC conversion results and/or fault flags in reg-
isters. Select the critical fault configuration in r6Dh[1:0].
Set r6Dh[1:0] to ‘11’ to turn off the fault logger. All stored
ADC results are 8 bits wide.
