4.2.8 Block Clock Control Register 2 (BCKCON2)
BCKCON2 is a specific function register (SFR) to control supplying the clock of high-speed and low-speed to the
peripheral circuits.
The power consumption can be reduced by stopping the clock supply for unused peripheral circuits.
The bits are unwriteable when the products do not have the peripheral circuits and they return "0" for reading.
See Table 4-7 "Availability of the SFR bit symbols in BCLCONn register and BRECONn register".
