(1)
The t
pd
is dependent on the data pulse width (Pw), and Y outputs are changed after one-half of Pw, because the internal clock is synchronized
at the middle of the data pulse. Not tested, but specified by design.
(2)
When outputs are open collector (OUTSEL = L)
(3)
When outputs are push-pull (OUTSEL = H)
(4)
SOUT goes low when the data is received correctly and maintains a low level for one data-pulse period. Not tested, but specified by design.
