The MC56F825x/MC56F824x device is based on the 56800E core. It uses a dual Harvard-style architecture with two
independent memory spaces for data and program. On-chip RAM is shared by both data and program spaces; flash memory is
used only in program space.

If CLKIN is selected as the device’s external clock input, both the GPS_C0 bit in GPS1 and the EXT_SEL bit in the OCCS
oscillator control register (OSCTL) must be set. In this case, it is also recommended to power down the crystal oscillator.
