Section 15 USB Function Module (USB)

The endpoint number is the endpoint number the USB host uses. The endpoint FIFO number
corresponds to the endpoint number described in this manual. Thus data transfer between the USB
host and the endpoint FIFO can be enabled by putting the endpoint number and the endpoint FIFO
number in one-to-one correspondence. Note that the setting value is subject to a limitation
described below.
Since each endpoint FIFO number is optimized by the exclusive software that corresponds to the
transfer system, direction, and the maximum packet size, make sure to set the endpoint FIFO
number to the data described in table 15.2.
1. The endpoint FIFO number 1 cannot designate other than the maximum packed size of 8 bytes,
2. The endpoint number 0 and the endpoint FIFO number must have one-on one relationship.
3. The maximum packet size for the endpoint FIFO number 0 is 8 bytes only.
4. The endpoint FIFO number 0 can specify only the maximum packet size and the data for the
5. The maximum packet size for the endpoint FIFO numbers 1 and 2 is limited to 64 bytes.
6. The maximum packet size for the endpoint FIFO numbers 3 is limited to 8 bytes.
7. The maximum number of endpoint information setting is ten.
8. Up to ten endpoint information setting should be made.
9. Write 0 to the endpoints not in use.
Table 15.2 shows the example of limitations for the maximum packet size, the transfer method,
and the transfer direction.
