Description added
PLL Circuit 1: PLL circuit 1 has a function for multiplying the
clock frequency from the EXTAL pin or crystal oscillation circuit
by 6 (SH7751 and SH7751R) or 12 (SH7751R). Starting and
stopping is controlled by a frequency control register setting.
Control is performed so that the internal clock rising edge
phase matches the input clock rising edge phase.
