Maximum Packet Length
: This field indicates the maximum number of
bytes that can be sent to or received from an endpoint in a single data
packet. The maximum packet size for the full-speed and low-speed
devices is 64 B as defined in the Universal Serial Bus Specification
Rev. 2.0
Number of Bytes to Transfer
: This field indicates the number of bytes
that can be transferred by this data structure. It is used to indicate the
depth of the DATA field. The maximum total number of bytes for this
transaction is 4 kB.

1 —
Software updates to one when there is payload to be sent or
received even across ms boundary. The current PTD is active.
