TMS320F28388D: Number of available USB endpoint on TMS320F28388D

Part Number: TMS320F28388D
Other Parts Discussed in Thread: C2000WARE,

When we check the document "spruii0f.pdf" in the section 38.6.2 (USB_REGS Registers), there are registers listed for 4 available endpoints.

When we go see in the C2000ware library there are registers listed for 16 pairs of endpoints (in + out).

In the document "sprsp14e.pdf" in section 7.13.9 (Universal Serial Bus (USB) Controller), there is mention of 32 endpoints available (in + out) .

We would like to know if there is really a limit of 4 USB endpoints pairs for the TMS320F28388D processor ?

In our application we will use more than 4 endpoints pairs.

Thanks,

Sebastien
