Notes:
(1) Reset until clock pulse 18 (on declining flank).
Minimum integration time = (133-18) * CLK period + 10µs (this is the time the S&H cap needs to follow).
At 500kHz clock speed, the minimum integration time becomes 0.240ms.
(2) At 125°C, the integration time should be limited to 2ms.
(3) The SI pulse must go low before the rising edge of the next clock pulse.
