Method 1
All interrupt processing can be masked while the instruction is being executed.
Method 2

2. This is the program section from the interrupt subroutine:
Note 1. Define interrupt routines at the end of the main program with SBN(92) and
RET(93) instructions, just like regular subroutines.
2. When defining an interrupt routine, a "SBS UNDEFD" error will occur during
the program check operation, but the program will be executed normally.
