hello ; am using msp430 connected with atmel processor through spi . I need to detect the power failure of the processor to reset the msp430 but there is no way to do that , the only choice is to approximate the total time needed for the process and if exceeded reset the msp430 by wdt . My problem is that i found the appropriate time the process taken to be successfully executed is half an hour , which is not supported by the wdt intervals choices , and if i decided to use one of the msp430 timers there will be another problem that the maximum count value of the 16 bit count register is 65535 which means that even if i use the minimum frequency i will only get two minutes as maximum. any one have an idea please !!!
