Extension Instruction Specifications
3-38
<Error actualizing condition>
Error actualizing condition is generated by the first extension instruction executed in the interrupt program, or after
switching of the task. Error actualizing condition is shown below.
The error making potential condition is cleared when there is no problem.
When the condition of use corresponds to "Error generation", it is possible to solve the error condition by inserting
the 2 NOP instructions as follows.
When the program is compiled and assembled, 2 NOP instructions are inserted on default by using the assembler
and linker V3.3R1 or later.
CALLS or JSR instruction with stack area
outside internal RAM area
High-speed multiplication instruction
or Multiply-and-accumulate instruction
The case where the High-speed multiplication instruction uses 32-bit immediate value is excluded.
