What MCU are you using and are you jumper wiring this MCU to the ADS1262EVM? If so, would to be able to share picture of your hardware setup? Do you have the ability to use a /DRDY interrupt instead of polling the /DRDY pin? Likely you'd be able to control the timer with much more precision within an interrupt. Why the timer shows a data rate faster than 100 SPS doesn't make much sense, I'd expect it to show a slower data rate unless there is some configuration issue or false triggering of the timer. Would you also be able to share what the " ADS1262 _DRDY_PIN" macro is doing? Perhaps something about this macro is not working as expected.
