#114957 - 89s52-exit from power down using INT0 |
Hi every body,
i am doing a project using 89s52 and AD7799(24 bit adc) now to reduce the noise i thought of putting the micro off during coversion and tried to use the ready signal from the adc to wake the uC.the int0 was enabled using EX0, EA and configured as edge sensitive. but once the uC goes into power down , it doent respond at all( except for reset).Have i missed any thing? also any body has used the AD7799 and how is the performance and any giude lines-tricks for its design? thanks in advance dsu |
