Notes
1. Minimum value for I
2. Minimum value for I
3. Levels refer to pins PD11 to PD0, FSVGC, PIXCLKI, VSVGC, PIXCLKO, CBO, TVD, and HSVGC, being inputs or
4. The data is for both input and output direction.
5. This parameter is arbitrary, if PIXCLKI is looped through the VGC.
6. Tested with programming IFBP = 1.
7. If an internal oscillator is used, crystal deviation of nominal frequency is directly proportional to the deviation of
8.
