CHAPTER 6 CLOCK GENERATOR
Cautions 5. To change the value of EXCLK and OSCSEL, be sure to confirm that bit 7
(MSTOP) of the main OSC control register (MOC) is 1 (the X1 oscillator stops or
the external clock from the EXCLK pin is disabled).
6. To change the value of EXCLKS and OSCSELS, confirm that bit 5 (CLS) of the
processor clock control register (PCC) is 0 (the CPU is operating with the high-
speed system clock).
Remark f
: High-speed system clock oscillation frequency
