2.5.3.4. SDM I/O Pins for Power Management and SmartVID

SDM pins are also available for the SmartVID power management feature for -V and -E devices.

Intel recommends that you use LTC3888 or LTM4677 to regulate the PMBus. The LTM4677 device is the default setting for the Device > Device and Pin Options > Power Management & VID > Slave device type parameter. Select a regulator you use on your board. If you are using a different PMBus regulator, change the default setting from LTM4677 to Other.

Intel® Quartus® Prime Pro Edition software allows you to control the payload value of the Page command. Some PMBus devices contain more than one page per bank of registers, the Page command allows you to select the target Page per bank registers. The Page payload available range is between 0x00 and 0xFF.
Note: Prior the Intel® Quartus® Prime Pro Edition software release, the Page command selected all banks by default.
