FP_INTERRUPT_DISABLE

Deshabilitar programas de interrupción

Esta instrucción FP deshabilita la ejecución de todos los programas asignados a tareas de interrupción.

Observaciones

Si se está ejecutando un programa de interrupción mientras se ejecuta la instrucción, el programa de interrupción queda suspendido.
Usar FP_INTERRUPT_CLEAR_REQUESTS para borrar las señales de interrupción suspendidas por la unidad mientras la interrupción está deshabilitada.
Para deshabilitar o habilitar la interrupción de cada unidad, utilizar la instrucción FP_INTERRUPT_ACTIVATE.
