6-Channel, Flash-Configurable System Manager
with Nonvolatile Fault Registers
If GPIO6 is configured as the EXTFAULT input/output
and EXTFAULT is pulled low by an external circuit, bit
r1Ch[6] is set.
The SMB Alert ( ALERT ) bit is set if the MAX16068 has
asserted the SMBus Alert output. Clear by writing a ‘1’.
See the SMBALERT ( ALERT ) section for more details.
Table 12. Critical Fault Configuration
Critical Faults
During normal operation, a fault condition can be stored
in the flash memory by setting the appropriate critical
fault enable bits. Set the appropriate critical fault enable
bits in registers r6Eh–r72h (see Table 12) for a fault con-
dition to trigger a critical fault.
