PMBus COMMAND DESCRIPTION
MFR_PAGE_FF_MASK
The MFR_PAGE_FF_MASK command is used to select which channels respond when the global page command
(PAGE=0xFF) is in use.

MFR_I2C_BASE_ADDRESS
The MFR_I2C_BASE_ADDRESS command determines the base value for the I
2
C/SMBus address byte. Offsets of 0
to 9 are added to this base address to make the device I
2
C/SMBus address. The part responds to the device address.
MFR_I2C_BASE_ADDRESS Data Contents
BIT(S) SYMBOL OPERATION
b[7] Reserved Read only, always returns 0.
b[6:0] i2c_base_address This 7-bit value determines the base value of the 7-bit I
2
C/SMBus address. See Operation Section: Device Address.
