Classic DAS1602

ADC-sample per analog input sample event.
ADC-burst (one or more channels collected) per analog input sample event. Timing between ADC-samples within a burst are adjustable from 5 microseconds to 53 seconds to 25 nanosecond resolution.
Analog input sampling events enhanced from 3 to 13 possible sources.
Large FIFO depth allows for greater interrupt latency or readout latency.
Supports DMA (see note).

The DAS1602 mode is a step up from the DAS16jr/16 mode in that this mode additionally supports ADC-bursting. In other words, one sample strobe will produce and ADC-burst or one complete scan from the first_channel to the last_channel.

This mode typically uses the 8254 timer to set the sampling rate, however, other sampling sources can now be configured via the Analog Input General Configuration Register. The frame counter will actually count samples rather than frames, and the Analog Input Frame Timer will produce the timing for each sample rather than each frame.
