Figure 3.16.34 MPS (odd number) write access with max_pkt = even number (endpoint direct access)
4. Receive endpoint & endpoint direct access
5. Transmit endpoint & endpoint direct access
Either an odd or even number can be set in max_pkt. The access method is the same for both
cases.
Only an even number of bytes can be set in max_pkt. For the basic access method, refer to
To use an odd number of bytes as MPS for a transmit endpoint, the following settings are
required.
The following shows an example in which max_pkt = 1024 and the maximum number of bytes
(1023 bytes) are to be written.
• Set max_pkt = 1024.
• The maximum number of bytes that can be written to the endpoint is 1023 bytes. (It is not
• “wMaxPacketSize” of the Endpoint descriptor to be managed by firmware should be set to
• In the last access (1023rd byte), make sure that epx_w_be = 0y01.

1023. (This is the value to be sent to the USB host by the Get Descriptor request.)
