(1) In Gate Control mode, DRDY returns to high on the first falling edge of SCLK. In Pulse Control mode, DRDY remains low until the next
conversion is started. The DRDY pin or DRDY register bit can also be polled to determine when data are ready.
(2) CS may be held low.
(3) tUPDATE = 20/fCLK. Do not issue the Read Data opcode during this time.
(4) During this interval, DOUT does not follow DRDY (stop continuous mode).
(5) Optional conversion data checksum.
(6) Optional repeat of previous conversion data.
(7) DIN data are latched on the falling edge of SCLK. Data are output on the rising edges of SCLK.
(8) Read Data command = 012h.
