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. 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.
(Example: MPS = 1023)
Set max_pkt = 1024.
The maximum number of bytes that can be written to the endpoint is 1023 bytes. (It is not
allowed to write the 1024th byte.)
“wMaxPacketSize” of the Endpoint descriptor to be managed by firmware should be set to
1023. (This is the value to be sent to the USB host by the Get Descriptor request.)
In the last access (1023rd byte), make sure that epx_w_be = 0y01.
