Corrective Action
Check the program of the
CHK
instruction and correct it referring to
contents of detailed error codes.
Read the error step using a peripheral
device and delete the instruction.
IRET
Check the interrupt program if the
instruction is given in it.
Write the instruction if it is not given.
IRET
Monitor special register D9011 using a
peripheral device, and check if the
interrupt program that corresponds to the
stored data is provided or if two or more
interrupt pointers (I) of the same number
are given. Make necessary corrections.
