4.2 Flash interface settings
Please refer to section 2.4.2.2 ‘Flash access timing settings in CPU mode’ for the recommended Flash
interface settings.
4.3 Clock Modulator settings
The following table shows all possible settings for the Clock Modulator in a base clock frequency
range from 32MHz up to 80MHz.
Please note that Fmax must not exceed 80MHz.
The flash access time settings (see section 2.4.2.2) need to be adjusted according to Fmax while the
PLL and clockgear settings (see section 4.1) should be set according to base clock frequency.
