what happens to the I/O state during interrupts

Post by mynameispranay » Wed Apr 22, 2009 12:42 am

Hi again guys,
Well I am working with the Olimex MSP430-169LCd board based on MSP430F169 micro.

I was practicing interrupts and wanted to know what happens to the state of I/o pins when an ISR is called.

e.g if i have an LED light up at p2.0(0V= glow) and an an ISR is generated by P1.0 then what happens to the LED state?

Also , just to confirm....in ALL the low power modes the PREVIOUS I/o pin's status is unchanged?
