Note1: In receive mode, if the endpoint bits corresponding to packet-A or packet-Bare "1", read the required

packet-number data after checking EPx_SIZE<PKT_ACTIVE>.

Note2: In transmit mode, if both A and B bits are not "1", this means there is space in FIFO. So, write data of payload

or less to FIFO. If the transmission is short-packet, write "0" to EOP<EPn_EOPB> after writing data to the

FIFO. The maximum size that can be written to A or B packet is the same as the maximum payload size. If

both A and B bits are "0", continuous writing of double maximum payload size is available.

Note3: In dual packet transmit mode, if both A and B packet are empty and EOP<EPn_EOPB> is written "0", the

NULL-data is set to FIFO. In single mode, the NULL-data is also set to FIFO if the above operation is executed

when packet-A contains no data.

Note4:No data is set in this register when NULL-packet (0Length-packet) is received.
