ADS1296R: ADS1296R GPIO PORT CONFIGURE ISSUE

user4189183

Part Number: ADS1296R

I want to disable the internal respiration function of the ADS1296R and use an external circuit to measure the respiration. Then I want to use the gpio port to generate the clock signal at 64Khz.
Can the GPIO port generate a 64Khz clock signal? If so, can the GPIO1 to GPIO4 port be used like this?

    Hello,

    Thank you for your post and welcome to our forum!

    You can output the internal modulation clock, demodulation clock, and blocking signals by setting the last two bits in the RESP control register (16h) to 01b.

    For more information, please see section 9.3.1.7.8.1 in the datasheet.

    Best regards,
