eCAP Module for 4 Wire Stepper Motor Control in OMAP-l138

Hi

We are trying to using Mity-DSP-138F SOM module to 4 wire Stepper Motor Control.

eHRPWM Module outputs, we are unable to use as SPI1 SCS0 is used as CS for NOR Flash. So we are left to eCAP Modules as APWM outputs. (has only 3 outputs).

Our Stepper motor is one with 4 lead Wires. Can I able to control it through eCAP Module? In OMAP-L138 Reference Manual, It is shown 4 APWM outputs controlling 4 outputs. Can we synchronize all 3 APWM outputs ? How to generate the 4 APWM output?

If this is not possible, Can we have on 1 eHRPWM outputs( 0A/0B)  and two eCAP APWM outputs synchronized for 4 wire Motor Control?

Thanks and Regards,
