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
