Section 3 Oscillator Circuits and Operating Modes
If PLL circuit 1 or PLL circuit 2 does not become operational after modifying the frequency
modification register (including modification in the operating state), it means that the above
procedure or cautions have not been properly observed. In this case, the WDT will not operate
even though the frequency modification register is modified.
3.2.6
The following table shows the operating modes and the associated frequency ranges for input
clocks.
Notes: 1. When a crystal resonator is used, set the frequency in the range of 8 to 15.625 MHz.
