Notes: to calculate Z80 KIO daisy-chain timing, use the Z80 PIO, CTC, and SIO with I/O buffers on the chain. The
following are calculation formulas:
1. Parameter 18: M1 falling to IEO delay TdM1(IEO) = TdM1(IO)#1 + TdIEI(IEO)#2 + TdIEI(IEO)#3 + Output Buffer
2. Parameter 19: IEI to IORQ falling setup time TsIEI(IO) = TdIEI(IEO)#1 + TdIEI(IEO)#2 + TdIEI(IEO)#3 + Input
3. Parameter 20: IEI falling delay = TdIEI(IEOf) - TdIEI(IEOf)PIO + TdIEI(IEOf)CTC + TdIEI(IEOf)SIO + (Input buffer
4. Parameter 21: IEI rising to IEO rising delay (after ED decode) - TdIEI(IEOr) = TdIEI(IEOr)PIO + TdIEI(IEOr)CTC
