If you read the data bits between conversions, you can
1) count CLK cycles until the end of the conversion, or
2) poll EOC to determine when the conversion is
finished, or
3) generate an interrupt on EOC’s falling edge.
Note that the MSB conversion result appears at DOUT
after CS goes low but before the first SCLK pulse. Each
subsequent SCLK pulse shifts out the next conversion
bit. The 15th SCLK pulse shifts out the sub-LSB (S0).
Additional clock pulses shift out zeros.
Data is clocked out on SCLK’s falling edge. Clock data
in on SCLK’s rising edge or, for clock speeds above
2.5MHz, on the following falling edge to meet the maxi-
mum SCLK-to-DOUT timing specification (Figure 7).
The maximum SCLK speed is 5MHz. See the
Operating
Modes and SPI/QSPI Interfaces section for additional
information. When the conversion clock is near its maxi-
