DPID=B_0x0
OTG receive status debug read register
| EPNUM | Endpoint number Indicates the endpoint number to which the current received packet belongs. |
| BCNT | Byte count Indicates the byte count of the received data packet. |
| DPID | Data PID Indicates the data PID of the received OUT data packet 0 (B_0x0): DATA0 1 (B_0x1): DATA2 2 (B_0x2): DATA1 3 (B_0x3): MDATA |
| PKTSTS | Packet status Indicates the status of the received packet Others: Reserved 1 (B_0x1): Global OUT NAK (triggers an interrupt) 2 (B_0x2): OUT data packet received 3 (B_0x3): OUT transfer completed (triggers an interrupt) 4 (B_0x4): SETUP transaction completed (triggers an interrupt) 6 (B_0x6): SETUP data packet received |
| FRMNUM | Frame number This is the least significant 4 bits of the frame number in which the packet is received on the USB. This field is supported only when isochronous OUT endpoints are supported. |
| STSPHST | Status phase start Indicates the start of the status phase for a control write transfer. This bit is set along with the OUT transfer completed PKTSTS pattern. |
