[avr-gcc-list] problem in a3977 + avr micro stepping motor control driving

[Sach]

Hello friends,
I m working on a3977 micro stepping motor driver to control stepper motor
from www.allegromicro.com with avr microcontroller. 

In this, i m not able to change the micro stepping resolution for three
modes as shown below:  


MS1 MS2         Resolution
L      L            Full step (2 phase)
H      L           Half step
L      H           Quarter step
H      H           Eighth step

I m getting only the full micro stepping for any changes of Ms1 and Ms2
bits.
So please help me with this issue..

Regards,
sachin rathod,
Surat..
