Watchdog Timer
•
Software-configurable, two-stage Watchdog with programmable timeout
ranging from 125 ms to 4096 s in 16 steps
•
Serves for generating IRQ or hardware reset
System Timer
•
The Intel® QM77 chipset contains three 8254-style counters which have
fixed uses
•
In addition to the three 8254-style counters, the Intel® QM77 chipset
includes eight individual high-precision event timers that may be used
by the operating system. They are implemented as a single counter
each with its own comparator and value register.

Module Management
Controller
•
ARM7 microcontroller with redundant 512 kB Firmware Flash and auto-
matic roll-back strategy
•
The MMC carries out IPMI commands such as monitoring several
onboard temperature conditions, board voltages and the power supply
status, and managing hot swap operations.
•
The MMC is accessible via a local IPMB (IPMB-L) and one host Key-
board Controller Style Interface (KCS)
•
One MMC system EEPROM for FRU data and firmware private data
Hot Swap
The AM4022 has full hot swap capability.
