[CPU Mode Registers A, B (CPUMA, CPUMB)] 000016, 000116
The CPU mode register contains the stack page select bit and the
CPU operating mode select bit and so on.
The CPU mode registers are allocated at address 000016, 000116.

Notes 1: This is not available in the flash memory version.
2: When (CPMA 6, 7) = (0, 0), the internal system clock can be selected between f(XIN) or f(XIN)/2 by CCR7.
The internal clock
φ is the internal system clock divided by 2.
