(5) Ready Input Timing
CLK signal standards
(AVCC = VCC = 4.5 V to 5.5 V, AVSS = VSS = 0.0 V, TA = –30
°C to +70°C)
N: Stands for the number of wait cycles. With no wait, N is set at “0”. (The number of wait cycles depends on an
automatic wait and external RDY.)
* : For tCYC (cycle time (machine cycle)), see paragraph (4), “Clock output timing.”
Note: Use the automatic ready function when the setup time for the rising edge of the RDY signal is not sufficient.
