DESCRIPTION
The End-Or-Identify (
EOI
) line is one of five bus management lines on the IEEE 488 bus. It is used by a Talker to
indicate the end of a multiple byte transfer sequence. Using the End-Or-Identify (
K
) command, the controller can
enable or disable the
EOI
mode by programming the Digital488/80A from the bus. In mode
K0
, the
EOI
line is
asserted by the Digital488/80A on the last byte of every bus output string. In mode
K1
, the
EOI
function is disabled
(except when using the binary Data Formats
F4
and
F5
).
