a. Units in nanoseconds (ns) unless otherwise noted.
b. Parameter does not apply to Interrupt Acknowledge transactions.
c. Parameter applies only between transactions involving the SCC.
d. Float delay is defined as the time required for a ±0.5 V change in the output with a maximum DC load and a
minimum AC load.
e. Open-drain output, measured with open-drain test load.
f. Parameter is system dependent. For any Z-SCC in the daisy chain. TdAS(DSA) must be greater than the sum of
TdAS(IEO) for the highest priority device in the daisy chain TsiEI(DSA) for the Z-SCC, and TdIElf(IEO) for each device
separating them in the daisy chain.
g. Parameter applies only to a Z-SCC pulling INT Low at the beginning of the Interrupt Acknowledge transaction.
h. Internal circuitry allows for the reset provided by the ZB to be recognized as a reset by the Z-SCC. All timing
references assume 20 V for a logic “1” and 08 V for a logic “0”.
