What is the right way to read absolute encoders (SSI, BISS, ENDAT, etc.) with F28388D? Is it done using SPI in some way or are there more suitable peripherals?

We have used a combination of our SPI along with the CLB (configurable logic block) and some software to implement absolute encoder interfaces. In general the CLB controls the clocks required and the SPI is leveraged to send/receive frames. The CLB also takes care of any delay from the cable length.
The Tamagawa t-format: https://www.ti.com/tool/TIDM-1011 is available in the motor control SDK (https://www.ti.com/tool/C2000WARE-MOTORCONTROL-SDK).
The following are currently available in ControlSuite as a library for F2837xD.
