ADS1292: CLK pin state: can I connect it to gnd?

Part Number: ADS1292

Tool/software:

Hi! I am using the ads1292 IC and I would like to know if I can tie the CLK pin to ground using a pull-down resistor (100k ohms). I am not using external clock and I let the CLK_EN bit to default mode (without clock output in the CLK pin), so the CLK pin should be in 3-state mode, according to datasheet (page 28).

While we're in this subject, can I also tie START pin to ground so I can control the conversion by bus commands?

Best, Pedro.
