single-shot mode. The mode is selected by SINGLE_SHOT (bit 7 of the CONFIG1 register).
Single-Shot Mode
The single-shot mode is enabled by setting the SINGLE_SHOT bit in the CONFIG1 register to '1'. In single-shot mode, the ADS1291, ADS1292, and ADS1292R perform a single conversion when the START pin is taken high or when the START opcode command is sent. As seen in Figure 39, when a conversion is complete, DRDY goes low and further conversions are stopped. Regardless of whether the conversion data are read or not, DRDY remains low. To begin a new conversion, take the START pin low and then back high, or transmit the START opcode again. When switching from continuous mode to pulse mode, make sure the START signal is pulsed or issue a STOP command followed by a START command.
好象不是很麻烦呀
