PBUSY=0, SQSET=0, PID=00, SQMON=0, ACLRM=0, BSTS=0, SQCLR=0
Pipe 9 Control Register
| PID | Response PID 0 (00): NAK response 1 (01): BUF response (depending on the buffer state) 2 (10): STALL response 3 (11): STALL response |
| Reserved | These bits are read as 000. The write value should be 000. |
| PBUSY | Pipe Busy 0 (0): Pipe n not in use for the transaction 1 (1): Pipe n in use for the transaction. |
| SQMON | Sequence Toggle Bit Confirmation 0 (0): DATA0 1 (1): DATA1 |
| SQSET | Sequence Toggle Bit Set 0 (0): Invalid 1 (1): Specifies DATA1. |
| SQCLR | Sequence Toggle Bit Clear 0 (0): Invalid 1 (1): Specifies DATA0. |
| ACLRM | Auto Buffer Clear Mode 0 (0): Auto buffer clear mode is disabled. 1 (1): Auto buffer clear mode is enabled (all buffers are initialized) |
| Reserved | These bits are read as 00000. The write value should be 00000. |
