Notes to Microprocessor (μP) support.
1.
Possible ways to turn the ADM1041 on or off in response to a system request or a fault include:
?
?
?
Daisy chaining other ADM1041 PSON pins to the PEN pin, which is controlled by PSON on one ADM1041.
The microprocessor looks after the PSON—system interface and any shutdowns due to faults.
Connect all AC_OKLink pins together and connect all PS ON LINK pins together. These pins must be configured appropriately.
2.
Flags appended with _L are latched (Registers 2Ah/2Bh/2Ch). The latch is reset when the flag is read, except when the fault is still
present. It is advisable to continue reading the flag(s) until the fault(s) have cleared.
