Fourth revision: This message format supports the USA28XG
Buffer formats for RX/TX data messages are not defined by
a structure, but are described here:
USB OUT (host -> USAxx, transmit) messages contain a
REQUEST_ACK indicator (set to 0xff to request an ACK at the
completion of transmit; 0x00 otherwise), followed by data:
RQSTACK DAT DAT DAT ...
with a total data length of up to 63.
USB IN (USAxx -> host, receive) messages begin with a status
byte in which the 0x80 bit is either:
(a) 0x80 bit clear
indicates that the bytes following it are all data
bytes:
STAT DATA DATA DATA DATA DATA ...
for a total of up to 63 DATA bytes,
or:
(b) 0x80 bit set
indiates that the bytes following alternate data and
status bytes:
STAT DATA STAT DATA STAT DATA STAT DATA ...
for a total of up to 32 DATA bytes.
The valid bits in the STAT bytes are:
OVERRUN 0x02
PARITY 0x04
FRAMING 0x08
BREAK 0x10
Notes:
(1) The OVERRUN bit can appear in either (a) or (b) format
messages, but the but the PARITY/FRAMING/BREAK bits
only appear in (b) format messages.
(2) For the host to determine the exact point at which the
overrun occurred (to identify the point in the data
stream at which the data was lost), it needs to count
128 characters, starting at the first character of the
message in which OVERRUN was reported; the lost character(s)
would have been received between the 128th and 129th
characters.
(3) An RX data message in which the first byte has 0x80 clear
serves as a "break off" indicator.
