9.2.3
If the external RCON pin is asserted during reset, then the states of these data pins during reset
determine the chip mode of operation, boot device, clock mode, and certain module configurations
after reset.
9.3
This subsection provides a description of the memory map and registers.
9.3.1
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 can be read and written while in debug mode. When debug 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 mode, the register bit remains writable on exit from
debug or test mode.
9.3.2
Freescale Semiconductor
• The chip configuration register (CCR) controls the main chip configuration.
• The reset configuration register (RCON) indicates the default chip configuration.
• The chip identification register (CIR) contains a unique part number.
