Hello everybody ,
we are using a G2553 in 32 pin package in an industrial application , on same pcb some lines are connected to AC lines ( 220V 50Hz AC , or 110V 60 Hz AC) . Due to space constrains ,AC lines are running very closely to the MSP430 and these lines can be extremely noisy due to loads swicthing over the AC lines .
Now since the TDO,TDI,TMS,TCK go to a connector , these lines can act as antennas ...
we are now following " Table 2-3. Connection of Unused Pins " in sla144j , so pins are left unconnected .
we do not have issue on low power consumption , but we a need " the strongest " to noise system .
question : do we have to stay on previous table , or any suggestion for a differnent termination of these lines ?
thank you
bye
Carlo
