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).

3.2 Embedded PCI Functions
The “Device ID” field indicates that the device is for VME products (00) and
indicates the supported embedded feature set.
The “Vendor ID” and “Subsystem Vendor ID” fields indicate Abaco’s PICMG
®
assigned Vendor ID (114A).
The “Subsystem ID” field indicates the model number of the product (7768).
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
.
