3.1.2 I C/SMBus Temperature Sensor
The MAX6657MSA can be monitored and controlled on the SMBus at address
0x98 for the VMIVME‐7807/VME‐7807RC. This will allow the user to monitor and
set up the two alarms available (ALERT and OVERT1).
For more information on the Maxim MAX6657MSA contact them directly at:
1‐888‐629‐4642, or visit Maxim's website at www.maxim‐ic.com.
The VMIVME‐7807/VME‐7807RC provide non‐volatile RAM (NVRAM), timers
and a Watchdog Timer via the PCI bus. These functions are required for
embedded and real time applications. The PCI configuration space of these
embedded functions is shown in Table 3‐1.
