Hi!
The code provided by the microchip for 3 Phase Induction motor control ,in this code they are using Sine look up, but from the code I don't understand that how they are taking the values for 3 phase which are 120 degree apart from each other from single Sine Look Up table which is from 270 degree to 90 degree with 10 Degree Resolution.
They are using the 3 offset pointer for 3 phases but what is the method of taking 3 values with the help of offset register which are 120 degree apart from each other from single SIN look up Table.

 Please explain me if anybody read this code from application note "AN889".

Any kind of help will be highly appreciated.

Regards
