Note:
1. Parameter does not apply to Interrupt Acknowledge transactions.
2. Parameter applies only between transactions involving the ESCC.
3. Open-drain output, measured with open-drain test load.
4. Parameter is system-dependent. For any ESCC in the daisy chain, TdIAi(RD) must be greater than the sum of
5. Parameter applies to enhanced Request mode only (WR7’ bit 4=1)
6. Units in nanoseconds.
7. Units in TcPc.
TdPC(IEO) for the highest priority device in the daisy chain. TsIEI(RDA) for the ESCC and TdIEI(IEO) for each
device separating them in the daisy chain.
