PRODUCTION DATA
One-shot control mode initiates a single conversion when START is taken high or, through SPI operation, when the START bit of the CONTROL register is set to 1b. DRDY drives high to indicate the conversion is started and drives low when the conversion is complete. Data are available for readback at that time.
Taking START low, or writing 1b to the STOP bit, does not interrupt the ongoing conversion. The STOP bit has no effect. To restart the conversion, pulse START low to high, or write 1b to the START bit a second time. Figure 8-27 shows the one-shot control mode operation. In standby mode, DRDY returns high three clock cycles after transitioning low, otherwise DRDY remains low until forced high at the next rising edge of START.
