BAR2: Analog to Digital Converter (ADC) 

This Function Block is for the Analog to Digital converter.  The DM34216 has four ADC Function blocks, one for each of the four ADC inputs.  
The ADC0 input is associated with the lowest-numbered ADC Function Block, and ADC3 is associated with the highest-numbered ADC 
Function Block.  Each Function Block has its own clock, triggers, and DMA channel.

Selects the current mode of operation and indicates its triggering status.

0x04: Uninitialized.  This is the power-on state.  No converter initialization has taken place.  Sampling is stopped, and all 
counters are reset, and the triggering state machine is reset.  Transition to any of the other Modes will start converter 
initialization (sampling will not start until initialization is complete). 

o

 

0x00: Reset.  Sampling is stopped.  All counters are reset, and the triggering state machine is reset. 

o

 

0x01: Paused.  Sampling is stopped, but the counters and triggering state machine maintain their state. 

o

 

0x02: Go, Single-Shot.  After filling the buffer with the Post-Stop samples, capturing stops.  The Mode must be set back 
to RESET in order to capture more samples. 

o

 

0x03: Go, Re-arm. After filling the buffer with the Post-Stop samples and the FIFO is empty, the triggering state machine 
is restarted, i.e. FIFO is filled with Pre-Start samples and waits for a start trigger.
