Endpoints and FIFOs
In the ML60852, it is possible to select by making appropriate register setting either 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.

FIFO Capacity: The unit is bytes.
Note 1: The selection between the 5EP mode and the 6EP mode is made by bit D2 of the register
SYSCON.
Note 2: EP3 permits rate feedback data sequence toggling.
Note 3: EP1, EP2, and EP3 are all mutually independent, and can be assigned for bulk transfer or
interrupt transfer individually. It is possible to set the maximum packet size up to 64 bytes (32
bytes for EP3) during both bulk transfer and interrupt transfer.
Note 4: It is possible to set EP4 and EP5 to one of the modes of isochronous transfer, bulk transfer, and
interrupt transfer. The maximum packet size can be up to 64 bytes when these end points are set
to bulk transfer.
Note 5: When using EP4 and EP5 in the isochronous transfer mode:
In the 5EP mode, the maximum packet size of EP4 is 512 bytes. EP5 cannot be used.
In the 6EP mode, the maximum packet size of both EP4 and EP5 is 256 bytes.
