current comparison.
Note: In FAST DECAY MODE, too, CHARGE MODE is entered momentarily due to current comparison.
When CLK signal is input, the chopping counter (CR-CLK counter) is forced to reset at the next CR-CLK
Because of this, compared with a method in which the counter is not reset, response to the input data is
The delay time, the theoretical value in the logic portion, is expected to be a one-cycle CR waveform: 5 μ s
When the CR counter is reset due to CLK signal input, CHARGE MODE is entered momentarily due to
