Timing Waveform of Mux’d Port Write to Non-Mux’d Port Read

NOTES:

1.

CE, UB/LBn = VIL; CNTEN and CNTRPT = VIH.

2.

OE = VIL for Port, which is being read from. OE = VIH for Mux’d Port, which is being written to.

3. If tCO < minimum specified, then data from Non-Mux’d Port read is not valid until following Non-Mux’d Port clock cycle (i.e., time from write to valid read on opposite port will be tCO + 2

tCYC2 + tCD2). If tCO > minimum, then data from Non-Mux’d Port read is available on first Non-Mux’d Port clock cycle (i.e., time from write to valid read on opposite port will be tCO + tCYC2

+ tCD2).
