These bits are valid when the EP0 is set to continuous transmit mode (CTRR bit = “1”) at the time of control
read transfer (ISEL bit = “1”).
These bits set the total byte count of the data transmitted (over multiple transactions) during data stage of
control read transfer.
These bits can be set to maximum 256 bytes. When total byte count exceeds 256, set the 256 bytes and the
excess byte in several cycles.
When the integral multiples of the value set by the EP0 Packet Size Register is set to these bits, the zero-
length packet is automatically added after all data are transmitted. The zero-length packet is not
automatically added if the SDLN are set to 256 to transmit 256 bytes data or more.
Write to the buffer after setting this bit. Set these bits before writing to the buffer.
