(5) Main OSC control register (MOC)
R01UH0028EJ0400 Rev.4.00
Sep 27, 2010
This register selects the operation mode of the high-speed system clock.
This register is used to stop the X1 oscillator or to disable an external clock input from the EXCLK pin when the CPU
operates with a clock other than the high-speed system clock.
MOC can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets this register to 80H.
Address: FFA2H

2. When setting MSTOP to 1, be sure to confirm that the CPU operates with a clock
