2 EO
Output from PLL frequency synthesizer charge pump.
The division value of the local oscillation frequency
and the phase of the reference frequency are
compared at this pin, and the result is output.

these pins. When only the CPU is operating, 3.5 to
5.5 V is supplied to these pins. 2.3 to 5.5 V is supplied
when the clock is stopped. The same potential voltage
is supplied to VDD1 and VDD2.
