Correction Request: AN2867 Oscillator design

Rev 19 Page 16/59:I believe this should read "increase" instead. The purpose of Rext is to limit the current and thus lower power dissipation in the crystal. So, lowering Rext increases power dissipation. A separate issue is that this phrase is awkwa...
