Serial interface RESET input.
When using the serial interface mode, the user MUST initialize internal registers
through hardware RESET by applying a high-going pulse on this pin, or by using
the software reset option. See the SERIAL INTERFACE section.

In parallel interface mode, the user has to tie RESET pin permanently HIGH.
(SDATA and SEN are used as parallel pin controls in this mode).
The pin has an internal 100-k
Ω pull-down resistor.
This pin functions as serial interface clock input when RESET is low.
It functions as LOW SPEED control pin when RESET is tied high. Tie SCLK to

LOW for Fs > 50 MSPS and SCLK to HIGH for Fs
≤ 50 MSPS. See Table 3.
The pin has an internal 100-k
Ω pull-down resistor.
