27.4.3
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.
27.5
This subsection provides a description of the memory map and registers.
27.5.1
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.

S = CPU supervisor mode access only. User mode accesses to supervisor only addresses have no effect and result in a cycle
termination transfer error.

this register.
Writing to reserved addresses with values other than 0 could put the device in a test mode; reading returns 0s.
