+
+ 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.
+
+ revision history:
+
+ 1999feb10 add reportHskiaChanges to allow us to ignore them
+ 1999feb10 add txAckThreshold for fast+loose throughput enhancement
+ 1999mar30 beef up support for RX error reporting
+ 1999apr14 add resetDataToggle to control message
+ 2000jan04 merge with usa17msg.h
+ 2000jun01 add extended BSD-style copyright text
+ 2001jul05 change message format to improve OVERRUN case
+ 2002jun05 update copyright date, improve comments
+ 2006feb06 modify for FX1 chip
