(3) Endpoints and FIFOs

In the ML60852, it is possible to select, by making appropriate setting in the SYSCON register, the 5EP mode in

which there are five end points or the 6EP mode in which there are six end points. Although the transfer mode that

can be used by EP0 is fixed, it is possible to select either the bulk transfer mode or the interrupt transfer mode for the

end points EP1, EP2, and EP3, and one of the modes of isochronous, bulk, or interrupt transfer can be selected for

EP4 and EP5. In addition, it is possible to selectively set the direction of data transfer for EP1 to EP5.
