Hi everyone, Any ideas why it appears that in the PCON register if I have the /PDBOD bit set when I set the PD bit, the processor does not wakeup and resume execution as expected. This happens if I write an 0x06 to PCON ... OR first write a 0x04 followed by a 0x02 (the 0x02 finally putting into power down mode). Setting the /PDBOD bit along with the PD is suppose to disable brown out detect during power down mode. - using EINT1 to generate wakeup condition (this part seems to work fine) - if both bits are set seems wake up and appears to start code execution at 0x0 (like a complete reset happened) - but this complete reset behavior isn't consistent - if only the PD bit is set when entering power down the EINT1 wakes up and code execution resumes as expected - have shown the behavior whether EINT1 generates an actual IRQ that the VIC services or if I just have code resume on the next instruction Anybody know what I'm missing?
