tCP, tCPB (internal operating clock cycle time): Refer to â(1) Clock Timing Rating.â
*1: tCYC is a frequency for 1 clock cycle including a gear cycle.
Use the doubler when CPU frequency is above 25 MHz.
*2: Rating at a gear cycle of à 1.
When a gear cycle of 1/2, 1/4, 1/8 is selected, substitute ânâ in the following equations with 1/2, 1/4, 1/8,
respectively.
Min : (1 â n/2) Ã tCYC â 10
Max : (1 â n/2) Ã tCYC + 10
Select a gear cycle of à 1 when using the doubler.
*3: Rating at a gear cycle of à 1.
When a gear cycle of 1/2, 1/4, 1/8 is selected, substitute ânâ in the following equations with 1/2, 1/4, 1/8,
respectively.
Min : n/2 Ã tCYC â 10
Max : n/2 Ã tCYC + 10
Select a gear cycle of à 1 when using the doubler.
