MFR_GPIO_RESPONSE
This command determines the controller’s response to the GPIOn pin being pulled low by an external source.
VALUE
MEANING
0xC0
GPIO_INHIBIT The LTC3880 will three-state the output in response to the GPIO pin pulled low.
0x00
GPIO_IGNORE The LTC3880 continues operation without interruption.
The device also:
Sets the NONE_OF_THE_ABOVE bit in the STATUS_BYTE
Sets the MFR bit in the STATUS_WORD
Sets the GPIOB bit in the STATUS_MFR_SPECIFIC command, and
Notifies the host by asserting ALERT pin. The ALERT pin pulled low can be disabled by setting bit[1] of MFR_CHAN_
CFG_LTC3880.
This command has one data byte.

USER_DATA_00 through USER_DATA_04
These commands are non-volatile memory locations for customer storage. The customer has the option to write any
value to the USER_DATA_nn at any time. However, the LTpowerPlay software and contract manufacturers use some of
these commands for inventory control. Modifying the reserved USER_DATA_nn commands may lead to undesirable
inventory control and incompatibility with these products.
These commands have 2 data bytes and are in register format.
