Description
Note amended
Note: * Do not use this setting.
Newly added
Using an External Clock: It is necessary to allow time for the PLL circuit to
stabilize. Therefore, the standby time should be set to a value of 2 ms or
greater.
Note amended
Note * Subclock functions are available in the H8S/2626 Series.
See section 20.7, Subclock Oscillator, for the method of fixing pins OSC1
and OSC2 when not used.
Note *2 deleted from MSTPC5
