(Note 2)

8 ! 109

f(f2)

(Note 2)

Notes 1: This is applied when the main clock division selection bit = “0” and f(f2) = 6 MHz.

2: f(f2) represents the clock f2 frequency.

For the relationship with the main clock and sub clock, refer to Table 14.3.1.

3: The TAiIN input cycle time must be 4 cycles of a count source or more.

The TAiIN input high-level pulse width and low-level pulse width must be 2 cycles of a count source

or more, respectively.
