ADuC7060/61: Absolute Maximum Ratings: Max current for all I/O ppins and for GND_SW pin?

What is the maximum rated current allowed to be sourced/sinked by the digital I/O pins?


What is the max current for the GND_SW pin?

What is the max current for the GND_SW pin that would not upset operations of the A/D? (For example, when primary A/D is converting some value, and the GND_SW is used to power-up an RTD circuit, per ADI app notes, and connected to the secondary A/D.... The RTD circuit excitation current will get injected onto the die -- will it upset operations for the primary A/D that is measuring a voltage unrelated to the RTD circuit? How much current into the GND_SW pin can be tolerated?)
