3.1.2 I C/SMBus Temperature Sensor
The MAX6659MEE can be monitored and controlled on the SMBus at address
0x98 for the V7768/V7769. This will allow the user to monitor and set up the
alarm (OVERT2).
For more information on the Maxim MAX6659MEE contact them directly at:
1-888-629-4642, or visit Maxim's website at www.maxim-ic.com.
The V7768/V7769 provide non-volatile RAM (NVRAM), timers and a Watchdog
Timer via the PCI bus FPGA. These functions are required for embedded and real
time applications. The PCI configuration space of these embedded functions is
shown in Table 3-1.
