This section lists and describes the System Control Block (SCB) registers, in numerical order by address offset. The SCB registers can only be accessed from privileged mode.
All registers must be accessed with aligned word accesses except for the FAULTSTAT, SYSPRI1, SYSPRI2, and SYSPRI3 registers, which can be accessed with byte or aligned halfword or word accesses. The processor does not support unaligned accesses to system control block registers.
Table 2-23 lists the memory-mapped registers for the SCB. All register offset addresses not listed in Table 2-23 should be considered as reserved locations and the register contents should not be modified.
