METHOD FOR RECEIVING AND DELIVERING DATA BETWEEN INTERRUPTION ROUTINES

摘要

PROBLEM TO BE SOLVED: To receive and deliver data between interruption routines while reducing an interruption inhibition processing and without imprudently affecting the other routine. SOLUTION: The interruption routine of a high priority order and the interruption routine of a low priority order are provided with dedicated variables a1 and a2 for data receive and deliver and the processing parts of the interruption routine of the high priority order and the interruption routine of the low priority order can not use the variables a2 and a1 respectively. First, the interruption routine of the high priority order sets the data to be delivered to the interruption routine of the low priority order to the variable a1. The interruption routine of the low priority order copies the data of the variable a1 to the variable a2 in an interruption inhibition section at the head. The interruption routine of the low priority order refers to the data of the variable a2 and performs a processing thereafter.
