DPID
Bits 30:29 DPID: Data PID
Bits 28:19 PKTCNT: Packet count
Bits 18:0 XFRSIZ: Transfer size
OTG_FS host channel-x transfer size register (OTG_FS_HCTSIZx) (x = 0..7,
where x = Channel_number)
Address offset: 0x510 + (Channel_number × 0x20)
Reset value: 0x0000 0000
Bit 31 Reserved
The application programs this field with the type of PID to use for the initial transaction. The
host maintains this field for the rest of the transfer.
This field is programmed by the application with the expected number of packets to be
transmitted (OUT) or received (IN).
The host decrements this count on every successful transmission or reception of an OUT/IN
packet. Once this count reaches zero, the application is interrupted to indicate normal
completion.
For an OUT, this field is the number of data bytes the host sends during the transfer.
For an IN, this field is the buffer size that the application has reserved for the transfer. The
application is expected to program this field as an integer multiple of the maximum packet size
for IN transactions (periodic and non-periodic).
