NOTES: 13. The pulse width of the CSTART must be not less than the required sampling time.
The delay from CSTART rising edge to following CSTART falling edge must be not less than the required conversion time.
The delay from CSTART rising edge to the INT falling edge is equal to the conversion time.
14. The maximum rate of SCLK is 25 MHz for normal long sampling and 10 MHz for normal short sampling.
