(3) Peripheral Enable Register 2 (PER2)
The PER2 register is used to enable or disable supplying the clock to the peripheral hardware. Clock supply to the hardware
that is not used is also stopped so as to decrease the power consumption and noise.
To use the peripheral functions which are controlled by this register, set (1) the bit corresponding to each function before
specifying the initial settings of the peripheral functions.
This register can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets this register to 00H.
