Endpoint5-0 buffer
not ready
interrupt
To IN/OUT token of each endpoint, if the set of response PID is not
NAK("00") and if buffer is in not ready state (receive/transmit disabled),
the bit which corresponds to the number of endpoint changes to "1".
(If the endpoint is control transfer or bulk transfer or interrupt transfer,
NAK response is executed)
If the endpoint is set to isochronous transfer, M66290A does not execute
NAK response, but when over-run or under-run of endpoint buffer
occurred, this bit changes to "1" at the timing of token packet receive end.
If it is set to isochronous (OUT), and if received data has error such as
CRC, this bit changes to "1" at the timing of transaction end.
When "0" is written, status flag is cleared.
When "1" is written, flag is not changed.
