ADS6149: How to connect RESET pin

Olivier Bernard
Prodigy 10 points
Part Number: ADS6149

I'm currently working on the design of a circuit using the ADS6149 and I would like to know how to connect the Reset pin. I will use the Serial Interface Configuration.

But I am confused about how the registers are reset .. in the datasheet (p.14), it's written that registers can be reset by 2 methods = Pulse on RESET pin, or via registers.

But, how can we reset via register when the SPI is not even configured ... ?

 

So is it necessary to apply a pulse on the reset pin the first time = to have a Button or GPIO ?

Thanks !

    Olivier,

    When RESET is low at power-on the communication interface is enabled (SEN, SDATA, SCLK) and requires no additional configuration.

    So, you are able to communicate even when the RESET is low in order to access the register reset function to begin setup of the device.

    The RESET pin can be held low for the entire operation if your application is only serial. The high-going pulse on RESET is included as an optional/alternate hardware reset control option in serial mode.

    Regards,
