Peripheral operating requirements and behaviors
In case the reciprocal of SCALER is an integer, the duty cycle of NFC clock is 50%,
means T
For example, if SCALER is 0.2, then T
However, if SCALER is 0.667, then T

The reciprocal of SCALER must be a multiple of 0.5. For
example, 1, 1.5, 2, 2.5, etc.
