5.3.3
When an interrupt is generated with the MIE flag set to “1”, the following processing is executed by hardware and the
processing of program shifts to the interrupt destination.
When an interrupt is generated regardless of the state of MIE flag, the following processing is performed by hardware
and the processing of program shifts to the interrupt destination.
A software interrupt is generated as required within an application program. When the SWI instruction is performed
within the program, a software interrupt is generated, the following processing is performed by hardware, and the
processing program shifts to the interrupt destination. The vector table is specified by the SWI instruction.
Reference:
For the MIE flag, Program Counter (PC), CSR, PSW, and ELEVEL, see “nX-U8/100 Core Instruction Manual”.
(1) Transfer the program counter (PC) to ELR1.
