10.1 Layout Guidelines

Connect a minimum of 1-µF or greater capacitor close to the power supply pins. Connect other capacitors and resistors according to the calculations (for example, the pullup resistors should be connected at various pins, the c capacitors should be connected at lock detect, and so forth.)
