Timer

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.

IPMI

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.
