1 Typical data was characterized at 5.0 V, 25°C or is recommended value.
2 The input clock source must be divided using RDIV to within the range of 31.25 kHz to 39.0625 kHz.
3 This parameter is characterized and not tested on each device. Proper PC board layout procedures must be followed to achieve
specifications. This data will vary based upon the crystal manufacturer and board design. The crystal should be characterized
by the crystal manufacturer.
