TMDSCNCD28335: Interface of SSI encoder to F28335 ControlCARD

Hello,

I am using F28335 ControlCARD to implement control algorithm for motor drive system. I am using SSI encoder (without incremental output) to read the rotor position.

I will be appreciated if anyone can help me to answer the following question:

1- What are the interface circuits needed to connect the encoder to the DSP F28335?

2- Are there ready codes or built-in functions to be used to read the signals (after the interface circuit) inside DSP F28335? 

Thanks in advance

Mahmoud
