ES2/EX2 SS2 SA2SE SX2

Pointer P is used with API 00 CJ and API 01 CALL instructions. The use of P does not need to start from P0, and the No. of P cannot be repeated; otherwise, unexpected errors may occur. For other information on P pointers, please refer to section 2.12 in this manual

Program example 1:

Explanations:

A interruption program has to start with a interruption pointer (I□□□) and ends with API 03 IRET. I instruction has to be used with API 03 IRET, API 04 EI, and API 05 DI. For detailed information on interrupt pointes, please refer to section 2.12 in this manual
