Note that a change in the SAMPLES_FOR_AVG register will not be reflected in the average telemetry
measurements until the present averaging interval has completed. The default setting for AVGN is 0000,
therefore, the average telemetry will mirror the instantaneous telemetry until a value higher than zero is
programmed.
The SAMPLES_FOR_AVG register is accessed via the PMBus read / write byte protocol.

MFR_SPECIFIC_12: READ_AVG_VIN (DCh)
The READ_AVG_VIN command will report the 12-bit ADC measured input average voltage. If the data is not
ready, the returned value will be the previous averaged data. However, if there is no previously averaged data,
the default value (0000h) will be returned. This data is read with the PMBus Read Word protocol. This register
should use the coefficients shown in Table 41.

MFR_SPECIFIC_13: READ_AVG_VOUT (DDh)
The READ_AVG_VOUT command will report the 12-bit ADC measured current sense average voltage. The
returned value will be the default value (0000h) or previous data when the average data is not ready. This data is
read with the PMBus Read Word protocol. This register should use the coefficients shown in Table 41.

Value Meaning Default
0h – 0FFFh Average of measured values for output 0000h
voltage
MFR_SPECIFIC_14: READ_AVG_IIN (DEh)
The READ_AVG_IIN command will report the 12-bit ADC measured current sense average voltage. The returned
value will be the default value (0000h) or previous data when the average data is not ready. This data is read
with the PMBus Read Word protocol. This register should use the coefficients shown in Table 41.
