(3) Before executing interrupt programs
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.
Remark
Refer to the following manual for details of the IMASK and EI instructions.
