1 Data in Typical column was characterized at 5.0 V, 25 °C or is typical recommended value.
2 When ICS is configured for FEE or FBE mode, input clock source must be divisible 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.
4 Proper PC board layout procedures must be followed to achieve specifications.
