<1> Setting high-speed system clock oscillation
Check the OSTC register and wait for the necessary time.
During the wait time, other software processing can be executed with the internal high-speed oscillation clock.
Using AMPH, set the frequency to be used.
Note Set AMPH before setting the peripheral functions after a reset release. The value of AMPH can be
Remark f
When EXCLK and OSCSEL are set to 1, the mode is switched from port mode to external clock input mode.
When MSTOP is cleared to 0, the input of the external main system clock is enabled.
(See 6.6.1 (1) Example of setting procedure when oscillating the X1 clock and (2) Example of setting
procedure when using the external main system clock.)
Note The setting of <1> is not necessary when high-speed system clock is already operating.
