MOTOROLA
This subsection provides a description of the memory map and registers.
The CCM programming model consists of these registers:
Some control register bits are implemented as write-once bits. These
bits are always readable, but once the bit has been written, additional
writes have no effect, except during debug and test operations.
Some write-once bits and test bits can be read and written while in debug
mode or test mode. When debug or test mode is exited, the chip
configuration module resumes operation based on the current register
values. If a write to a write-once register bit occurs while in debug or test
mode, the register bit remains writable on exit from debug or test mode.
