READ_VOUT (8Bh)
The READ_VOUT command is a standard PMBus command that returns the 12-bit measured value of the output
voltage. Reading this register should use the coefficients shown in Table 41. Accesses to this command should
use the PMBus read word protocol. This value is also used internally for the VOUT Under-Voltage Warning
detection.

READ_TEMPERATURE_1 (8Dh)
The READ_TEMPERATURE_1 command is a standard PMBus command that returns the signed value of the
temperature measured by the external temperature sense diode. Reading this register should use the coefficients
shown in Table 41. Accesses to this command should use the PMBus read word protocol. This value is also
used internally for the Over-Temperature Fault and Warning detection. This data has a range of -256°C to +
255°C after the coefficients are applied.

MFR_ID (99h)
The MFR_ID command is a standard PMBus command that returns the identification of the manufacturer. To
read the MFR_ID, use the PMBus block read protocol.
