(1) Example of setting procedure when oscillating the X1 clock
(2) Example of setting procedure when using the external main system clock
(3) Example of setting procedure when using high-speed system clock as CPU clock and peripheral hardware
<1> Setting P121/X1 and P122/X2/EXCLK pins and selecting X1 clock or external clock (OSCCTL register)
<2> Controlling oscillation of X1 clock (MOC register)
<3> Waiting for the stabilization of the oscillation of X1 clock
Cautions 1. Do not change the value of EXCLK and OSCSEL while the X1 clock is operating.
<1> Setting P121/X1 and P122/X2/EXCLK pins and selecting operation mode (OSCCTL register)
<2> Controlling external main system clock input (MOC register)
Cautions 1. Do not change the value of EXCLK and OSCSEL while the external main system clock is
clock
<1> Setting high-speed system clock oscillation
When EXCLK is cleared to 0 and OSCSEL is set to 1, the mode is switched from port mode to X1 oscillation
mode.
If MSTOP is cleared to 0, the X1 oscillator starts oscillating.
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.
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.
(Refer to 5.6.1 (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.
