[CPU mode register (CPUM)]
The CPU mode register contains the stack page selection bit.
This register is allocated at address 003B16.
For this product, the clock speed of CPU is always f(XIN)/4.

Note : The bit can be rewritten only once after releasing reset.
After rewriting, it is disabled to write any data to this bit.
However, by reset the bit is initialized and can be rewritten, again.
It is not disabled to write any data to this bit for emulator MCU gM37545RLSS.h
