(4) Normal bus access read/write operation
(VCC
= 3.0 V to 3.6 V, VSS = DAVS = AVSS = 0 V, Ta = 0°C to + 70°C)
*1 : When the bus timing is delayed by automatic wait insertion or RDY input, add the time (tCYC
× the number of
cycles added for the delay) to this rating.
*2 : The following ratings are for the gear ratio set to 1. For the ratings when the gear ratio is set to between 1/2 to
1/8, substitute 1/2 to 1/8 for n in the following equation.
Calculation expression: 3/(2n)
× tCYC 15
