(7) Ready Input Timing
(AVCC = VCC = 5.0 V
±10%, AVSS = VSS = 0.0 V, TA = 0°C to +70°C)
Note: If the RDY setup time is insufficient, use the auto ready function.
(8) Hold Timing
(AVCC = VCC = 5.0 V
±10%, AVSS = VSS = 0.0 V, TA = 0°C to +70°C)
* : For information on tCYC (cycle time), see “(2) Clock Output Timing.”
Note: At least one cycle is required from the time when HRQ is fetched until HAK changes.
