6.22 High Speed Interrupt FunctionNote56 Note57
When an interrupt program is created using the interrupt pointer I49, the QnHCPU can run
a program by making high speed, fixed-cycle interrupts at intervals of 0.2ms to 1.0ms.
And, the QnHCPU improves the I/O response by refreshing the I/O signals and intelligent
function module buffer memories in the parameter-set ranges before and after the
execution of the high speed interrupt program.
This enables accurate control such as precision position detection.

The Q02CPU cannot use the high speed interrupt function.
When using the high speed interrupt function with the QnHCPU, check the versions of the CPU
module and GX Developer. ( Appendix 3.2)
