[2] The VIN_UV bit in the STATUS_WORD will have one automatic clearing after POR when the SPI UVLO_FAULT bit clears. [3] The VIN Under voltage fault bit in the STATUS_INPUT will have one automatic update after POR when the SPI UVLO_FAULT bit goes low. [4] The data for the MFR_ID command is shown first byte read to last byte read. [5] The MFR_ID can be changed with a metal option [6] The data for the MFR_MODEL command is shown first byte read to last byte read. [7] The MFR_MODEL can be changed with a metal option. [8] The data for the MFR_REVISION command is shown first byte read to last byte read. [9] The MFR_REVISION can be changed with a metal option. [10] The VIN_UV_FAULT bit in the ALERT_MASK will have one automatic update after POR when the SPI UVLO_FAULT bit clears. [11] BLOCK_READ does not have a default value, it is the concatenation of DIAGNOSTIC_WORD, MFR_READ_IIN, READ_VOUT, READ_VIN, MFR_READ_PIN, READ_TEMPERATURE_1. [12] The data for the BLACK_BOX_READ command is shown as first word received to last word received [13] The INPUT_UNDERVOLTAGE_FAULT bit in the DIAGNOSTIC_WORD will have one automatic update after the SPI UVLO_FAULT goes low.
