Doubts on Onchip Temperature Sensor and GPIO Pin?

Other Parts Discussed in Thread: TMS570LC4357

Hi TI,

I am using TMS570LC4357.

Q1) In the trm, it is mentioned that each GPIO pin has a seperate Output Buffer Drive Strength.

In some Pins, (Ex: F3) it is specified that Output Buffer Drive Strength for this pin is 2mA ZD. I do not know what this ZD means?

Can anybody specify the meaning of this notation?

Q2) TMS570LC4357 has internal Temperature sensor. But my doubt is whether this internal temperature sensor will sense ambient temperature or just the TMS570LC4357 Chip's Temperature (produced on running condition.)?


Please anybody clarify my doubts.

Thanks in advance.

Regards,
