The frequency divider is a programmable divider that generates the carrier frequency for the full-bridge antenna drivers. The default value for the division factor is the value 119 needed to provide the nominal carrier frequency of 134.45 kHz generated from 16 MHz. The resolution for programming the division factor is one divider step that corresponds to a frequency shift of approximately 1.1 kHz. The different division factors needed to cover the range of frequencies for meeting the resonance frequency of the transponder are 114 to 124.
