The base addresses of the CTI are not fixed, and can be different for any particular system implementation. However, the offset of any particular register from the base address is fixed. Each CTI has a 4KB programmer’s model and must be programmed separately. All unused memory space is reserved.
The following applies to all registers:
reserved or unused bits of registers must be written as 0, and ignored on a read unless otherwise stated in the text
all register bits are reset to 0 unless otherwise stated in the text
all registers must be accessed as words and so are compatible with little-endian and big-endian systems.
