A
read-data
time slot begins like a write-one time slot. The voltage on the data line must remain below
V
TLMIN
until the read low time t
RL
is expired. During the t
RL
window, when responding with a 0, the
DS1963S will start pulling the data line low; its internal timing generator determines when this pull-down
ends and the voltage starts rising again. When responding with a 1, the DS1963S will not hold the data
line low at all, and the voltage starts rising as soon as t
RL
is over.
The sum of t
RL
+ (rise rime) on one side and the internal timing generator of the DS1963S on the other
side define the master sampling window (t
MSRMIN
to t
MSRMAX
) in which the master must perform a read
from the data line. For most reliable communication, t
RL
should be as short as permissible and the master
should read close to but no later than t
MSRMAX
. After reading from the data line, the master must wait until
t
SLOT
is expired. This guarantees sufficient recovery time t
REC
for the DS1963S to get ready for the next
time slot.
