Hi,
I am Using PIC30F 5011 micro controller to handle different types of resets like POR and BOR and MCLR i am using terminal program.every time i am Power on the micro controller without pressing MCLR reset,
in hyper terminal showing results MCLR reset occurred.
my question is every time power up i expect POR and BOR only to flag but why does MCLR(EXTR) get flagged?
what happens if you reduce the voltage until it is not operational then raise it?
I would expect you to get a MCLR reset when you press the reset button and a POR reset when you switch on power (you may get an MCLR as well depending on the circuit)
I assume you have BOR enabled - what is the BOR reset trip point?
note that you are clearing the BOR bit (in the POR test) before testing it so it will never indicate if you get POR
i tried for BOR values at 2.0, 2.7 v, 4.2 and 4.7 as well.
but i when drop and raise voltages below BOR, MCLR doesnt get high.
but when i switch off - on RCONbits.EXTR gets flagged, but why ?
