OTG_FS Receive FIFO size register (OTG_FS_GRXFSIZ)
Address offset: 0x024
Reset value: 0x0000 0200
The application can program the RAM size that must be allocated to the RxFIFO.
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.
Indicates the status of the received packet
Indicates the Data PID of the received OUT data packet
Indicates the byte count of the received data packet.
Indicates the endpoint number to which the current received packet belongs.
This value is in terms of 32-bit words.
The power-on reset value of this register is specified as the largest Rx data FIFO depth.
0001: Global OUT NAK (triggers an interrupt)
0010: OUT data packet received
0011: OUT transfer completed (triggers an interrupt)
0100: SETUP transaction completed (triggers an interrupt)
0110: SETUP data packet received
