17.2.1 Operation
control to the handler routine.
430
If a non-maskable interrupt is generated by NMI input, the CPU performs the following processing, and transfers
<1> Saves the restored PC to FEPC.
<2> Saves the current PSW to FEPSW.
<3> Writes exception code 0010H to the higher halfword (FECC) of ECR.
<4> Sets the NP and ID bits of the PSW and clears the EP bit.
<5> Sets the handler address (00000010H, 00000020H) corresponding to the non-maskable interrupt to the PC,
The servicing configuration of a non-maskable interrupt is shown below.
