To take the simple block diagram of Figure 5 and reconfig- ure it to reuse the MS-Flash to do the LS-Flash is con- ceptually simple, but from a hardware point of view is not practical. A new six input switched capacitor comparator is used to accomplish this function in a simple, although not straightforward, manner.

Crystal Load Capacitors The device crystal connections should include pads for small capacitors from Xi to ground and from X2 to ground. These capacitors are used to adjust the stray capacitance of the board to match the nominally required crystal load capacitance. Because load capacitance can only be increased in this trimming process, it is important to keep stray capacitance to a minimum by using very short PCB traces (and no vias) been the crystal and device. Crystal capacitors must be connected from each of the pins Xl and X2 to ground.
