(3) Before executing interrupt programs
Remark
Note10
Basic Since the Basic model QCPU cannot execute multiple programs, interrupt programs cannot be
managed as another program.
Note3.10
(b) Managing interrupt programs as another program
Interrupt programs can be managed as one program (stand-by type program).
( Section 3.3.4)Note10
Before executing interrupt programs, execute the following instructions to enable the
interrupts.
(a) Basic model QCPU
Execute the EI instruction to enable the interrupts.
(b) High Performance model QCPU, Process CPU or Redundant CPU
When executing interrupt programs of interrupt pointers I32 to 47, execute the
IMASK and EI instructions to enable the interrupts.
The interrupt programs of interrupt pointers I0 to 31 or I48 to 255 can be executed
after enabling the interrupts with the EI instruction.
(c) Universal model QCPU
The interrupt programs of interrupt pointers I0 to 15, I28 to 31, I45, I50 to 255 can
be executed after enabling the interrupts with the EI instruction.
Refer to the following manual for details of the IMASK and EI instructions.
