tCP, tCPB (internal operating clock cycle time): Refer to “(1) Clock Timing Rating.”
*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 × 1.
When a gear cycle of 1/2, 1/4, 1/8 is selected, substitute “n” in the following equations with 1/2, 1/4, 1/8,
respectively.
Min : (1 – n/2) × tCYC – 10
Max : (1 – n/2) × tCYC + 10
Select a gear cycle of × 1 when using the doubler.
*3: 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 equations with 1/2, 1/4, 1/8,
respectively.
Min : n/2 × tCYC – 10
Max : n/2 × tCYC + 10
Select a gear cycle of × 1 when using the doubler.
