Byte 2 The buffer full ratio field indicates, on Read commands,
how full the drive’s buffer is before reconnecting. The drive
rounds up to the nearest whole logical block. This parame-
ter is the numerator of a fraction that has 256 as its
denominator.
Byte 3 The buffer empty ratio field indicates, on Write com-
mands, how empty the drive’s buffer is before reconnect-
ing to fetch more data. The drive rounds up to the nearest
whole logical block. This parameter is the numerator of a
fraction that has 256 as its denominator.
Bytes 4–5 The bus inactivity limit field indicates the time, in 100-
µ
sec
increments, that the drive can assert the Busy signal
without handshakes until it disconnects. The drive can
round down to its nearest capable value. If the bus inac-
tivity limit is 0000
H
, the drive maintains the BSY– signal
for 1 msec without handshakes.
Bytes 6–7 The disconnect time limit field indicates the minimum
time, in 100-
µ
sec increments, that the drive remains
disconnected until it attempts to reconnect. A value of 0
indicates that the drive is allowed to reconnect immedi-
ately.
Bytes 8–9 The
connect time limit field indicates the maximum time,
in 100-
µ
sec increments, that the drive should remain
connected until it attempts to disconnect. The drive may
round to its nearest capable value. A value of 0 means
that the drive can remain connected indefinitely until it
tries to disconnect.
