When the specified clock signal is input to the EXTAL pin, an internal clock signal output is
ensured after the external clock output stabilization delay time (t
signal output is not ensured during the t
reset state should be retained. Table 15.4 shows the external clock output stabilization delay time
and figure 15.6 shows the timing of the external clock output stabilization delay time.
Table 15.4 External Clock Output Stabilization Delay Time
Conditions: Vcc = 3.0 V to 3.6 V, Vss = 0 V
Note:
15.2
The PLL circuit has the function of multiplying the frequency of the clock from the oscillator by a
factor of 2. Therefore, a 16.5-MHz clock should be input to realize the internal 33-MHz operation.
The phase of the rising edge of the internal clock is controlled so as to match that of the rising
edge of the EXTAL pin.
