*1 : When bus timing is delayed by automatic wait insertion or RDY input, add (tCYC × extended cycle number for
delay) to this rating.
*2 : Rating at a gear cycle of × 1.
When a gear cycle of 1/2, 1/4, 1/8 is selected, substitute “n” in the following equation with 1/2, 1/4, 1/8, respectively.
Equation : (2 − n / 2) × tCYC − 40
