The minimum pulse width of SCLK high is 12.5 ns. The minimum pulse width of SCLK low is 12.5 ns.
Specified by design
NOTE 6: For normal short sampling, td(3) is the delay from 16th falling edge of SCLK to INT falling edge.
For normal long sampling, td(3) is the delay from 48th falling edge of SCLK to the falling edge of INT.
Conversion time, t(conv) is equal to 18 × OSC + 15 ns when using internal OSC as conversion clock, or 72 × tc(1) + 15 ns when external
SCLK is conversion clock source.
