Internal high-speed
oscillation clock
X1 clock
External main system clock
XT1 clock
External subsystem clock
Caution When switching the internal high-speed oscillation clock to the high-speed system clock, bit 2
Remarks 1. The number of clocks listed in Table 5-8 is the number of main system clocks before switchover.
The following lists the register flag settings for stopping the clock oscillation (disabling external clock input) and
Clock
(XSEL) of MCM must be set to 1 in advance. The value of XSEL can be changed only once after a
reset release.
2. Calculate the number of clocks in Table 5-8 by removing the decimal portion.
