I´m making electrodes for my MPR121 and I have a problem. For what are the resistors R1 and R2 tha you can find in KITMRP121EVM_SCH.pdf (pages 17 or 23), because those paths goes to the MC9S08Q68, but I don´t undertand It, and how to find the resistor values I need.

Sorry, I have a bad english and thanks for helping me.
