(6) Peripheral enable registers 0 (PER0)
These registers are used to enable or disable use of each peripheral hardware macro. Clock supply to the
hardware that is not used is also stopped so as to decrease the power consumption and noise.
PER0 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears theses registers to 00H.
Address: F00F0H
