Other Parts Discussed in Thread: MSP430G2452
I met a very curious problem. MSP430G2452 was my i2c slave.MCLK from DCOCLK , is 16Mhz. when the vcc is 3V~3.3v, i2c slave and my i2c master communicate very well and the stop flag generates ok. while i drop the vcc down to 2.8v,MSP430 is still responding inerrably to the master.but MSP430 now won't generate the stop flag again,even the vcc go back to 3.3V.
I don't know why.
