MSP430F2274 logic level during debug/program ?

Other Parts Discussed in Thread: MSP430F2274

Hi everyone,

I need an information about MSP430F2274 behavior during program session. Which are the logic level of the pins during this period (H,L,Hi-Z)?

Because I need to know if I have to insert in my circuit pull-up or pull-down to prevent unwanted logic level on some pins.

Thanks to all

Hi Andrea,

When you have not defined a pin as an output with a logic level, it is usually set as an input pin...then you could take it as Hi-Z...if you need a logic level during those unknown states I would suggest you using a pull up or pull down according to your needs.

Therefore, It should be taken into account when making your firmware and also (very important) estimating your power comsumption.

Since usually a program session is started with a device reset, the pins should be in BOR state. (high-Z)
