(3) Example of setting procedure when using high-speed system clock as CPU/peripheral hardware clock
<1> Setting P121/X1 and P122/X2/EXCLK pins (CMC register)
<2> Controlling external main system clock input (CSC register)
Cautions 1. The CMC register can be written only once after reset release, by an 8-bit memory
<1> Setting high-speed system clock oscillation
<2> Setting the high-speed system clock as the source clock of the CPU/peripheral hardware clock and
Remarks 1. ×: don’t care
When MSTOP is cleared to 0, the input of the external main system clock is enabled.
(See 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.
