... Interrupt Status reg- ister (Table 5). The ALERT output can also be masked by writing to the appropriate bits in the Interrupt Mask register (Table setting bit 1 of the Configuration register (Table 4) to zero. The MAX6683 SMBus/I compatible interface also responds to the SMB alert response address. Workstations ...

... C or SMBus capabilities can generate SMBus serial commands by “bit-banging” general-purpose input-output (GPIO) pins. The MAX6683 can monitor external supply voltages of typically 1.8V, 2.5V, 5V, as well as its own supply volt- age and temperature. This makes it ideal for supervisor and thermal management applications in telecommuni- cations, desktop and notebook computers, worksta- tions, and networking equipment ...
