(3) Setting of operation mode for subsystem clock pin
Note The main clock mode register (MCM) is used to set the main system clock supplied to CPU clock (high-
Caution
Remark
The operation mode for the subsystem clock pin can be set by using bit 6 (XTSTART) of the processor clock
control register (PCC) and bits 5 and 4 (EXCLKS, OSCSELS) of the clock operation mode select register
(OSCCTL) in combination.

Table 5-2. Relationship Between CPU Clock and Minimum Instruction Execution Time
Confirm that bit 5 (CLS) of the processor clock control register (PCC) is 0 (CPU is operating
with main system clock) when changing the current values of XTSTART, EXCLKS, and
