#145461 - redefine test Responding to: ???'s previous message |
For me re-entering/re-vectoring of any interrupt ,
prior RETI instruction is disabled in hardware. I dont know will be secondary edge "stored" for additional interrupt or not (as Mr.Malhund guess). Temporary change of priority (inside ISP) will block some other interrupt , not same - if You suppose ISR sets priority level for default executed code. Kernel, system, user levels- these are is related to operating systems and maybe not to 8051 hardware. So Alex - redefine Your test. regards |
