WRITING TELEMETRY DATA
There are several locations that will require writing data if their optional usage is desired. Use the same
coefficients previously calculated for your application, and apply them using this method as prescribed by the
PMBus revision section 7.2.2 "Sending a Value"
Y = (mX + b) x 10
R
(54)
Where:
X: the calculated "real-world" value (volts, amps, watts, temperature)
m: the slope coefficient, is the two byte, two's complement integer
Y: a two byte two's complement integer received from device
b: the offset, a two byte, two's complement integer
R: the exponent, a one byte two's complement integer
