The system registers control the status of the CPU and hold interrupt information.
These registers can be read or written by using system register load/store instructions (LDSR and STSR), using the
Notes 1. Because only one set of these registers is available, the contents of these registers must be saved by
Caution Even if EIPC or FEPC, or bit 0 of CTPC is set to 1 by the LDSR instruction, bit 0 is ignored when
