#146153 - need help P89V51RD2 Brown-out interrupt execution |
Hi Friends
I am writing software based on P89V51RD2 where I want to store count to External serial EEPROM in brown-out condition. I have set EBO bit at startup and have interrupt subroutine ( interrupt 9 with SDCC) at 0x4b for handling the situation.Processor does not interrupts in brown out condition but resets. I am using SDCC. On power on reset processor sends message to Host computer. In brown out condition i get same message instead of storing count. I have proper Serial EEPROM routines for read/write operation as it can read or write from serial EEPROM in normal condition. Thanks in Advance Bharat 9223464352 bharatprabhuAThathwayDOTcom |
