9.3.2 Operation speed mode control register (OSMC)
The RTCLPC bit can be used to reduce power consumption by stopping clock functions that are unnecessary. For
details about setting the RTCLPC bit, see CHAPTER 5 CLOCK GENERATOR.
Set the OSMC register by an 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
