If WP pin is high, PAGE, OPERATION, MFR_CLEAR_PEAKS, MFR_EE_UNLOCK and CLEAR_FAULTS commands are
supported. Individual fault bits can be cleared by writing a 1 to the respective bits in the STATUS registers.
MFR_ADDRESS
The MFR_ADDRESS command byte sets the 7 bits of the PMBus slave address for this device.
Setting this command to a value of 0x80 disables device addressing. The GLOBAL device address, 0x5A and 0x5B,
cannot be deactivated. If RCONFIG is set to ignore, the ASEL pin is still used to determine the LSB of the channel ad-
dress. If the ASEL pin is open, the LTC3880 will use the address value stored in NVM.
This command has one data byte.
MFR_CHANNEL_ADDRESS
The MFR_CHANNEL_ADDRESS command enables direct device address access to the PAGE activated channel. The
value of this command should be unique on the PMBus and should not be the same as another channel or device.
If this command is not set to 0x80, a status condition specific to this channel will result in the Alert Response Address
(ARA) value to be equal to the value of the MFR_CHANNEL_ADDRESS command.
Setting this command to a value of 0x80 disables channel device addressing for the channel.
This command has one data byte.
MFR_RAIL_ADDRESS
The MFR_RAIL_ADDRESS command enables direct device address access to the PAGE activated channel. The value
of this command should be common to all devices attached to a single power supply rail.
The user should only perform command writes to this address. If a read is performed from this address and the rail
devices do not respond with EXACTLY the same value, the LTC3880 will detect bus contention and set a CML com-
munications fault.
Setting this command to a value of 0x80 disables rail device addressing for the channel.
This command has one data byte.
