Capability for the EtherCAT Slave Controller which AM335x hardware has

I want to find out the capability for the EtherCAT Slave Controller which AM335x hardware has.

I watched wiki below.

http://processors.wiki.ti.com/index.php/AM335x_SYSBIOS_Industrial_SDK_01.00.00.04_Release_Notes

Above wiki describes the latest ISDK software and some boards (which are IDK and ICE).
Therefore, above wiki does not describe capability for the EtherCAT Slave Controller which AM335x hardware has.

I know that the capability for the EtherCAT Slave Controller depends on the EtherCAT software stack and PRU-ICSS firmware.
And the capability evolves by those update and is limited by AM335x hardware.

For the EtherCAT Slave Controller what can be supported by AM335x?

Can all functions which ET1100 has be supported by AM335x?

Best regards,

Daisuke
