16.3.4 Peripheral enable register 1 (PER1)
The PER1 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.
When using the DTC, be sure to set bit 3 (DTCEN) to 1.
The PER1 register can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
