Mode 0: An external clock is input from the EXTAL pin and undergoes waveform shaping by
PLL circuit 2 before being supplied inside the SH7708 Series. PLL circuit 1 is constantly on, and
there are no frequency range restrictions compared to mode 3. An input clock frequency of 8 MHz
to 60 MHz(SH7708, SH7708S) or 16 MHz to 60 MHz(SH7708R) can be used, and the CKIO
frequency range is 8 MHz to 60 MHz(SH7708, SH7708S) or 16 MHz to 60 MHz(SH7708R).
As PLL circuit 1 compensates for fluctuations in the CKIO pin load, this mode is suitable for
connection of synchronous DRAM.
