Description
Number of packets executed per transaction descriptor
00 - Execute N transactions as demonstrated by the USB variable
length protocol where N is computed using Max_packet_length
and the Total_bytes field in the dTD.
01 - Execute one transaction
10 - Execute two transactions
11 - Execute three transactions
Remark: Non-isochronous endpoints must set MULT = 00.
Remark: Isochronous endpoints must set MULT = 01, 10, or 11
as needed.
Zero length termination select
This bit is used for non-isochronous endpoints to indicate when a
zero-length packet is received to terminate transfers in case the
total transfer length is “multiple”.
0 - Enable zero-length packet to terminate transfers equal to a
multiple of Max_packet_length (default).
1 - Disable zero-length packet on transfers that are equal in
length to a multiple Max_packet_length.

Maximum packet size of the associated endpoint (< 1024)
Interrupt on setup
This bit is used on control type endpoints to indicate if USBINT is
set in response to a setup being received.
