Hi,
I am finding optimal register configuration for my application, and I got a problem that I cannot understand.
.
With the default 3-lead configuration (R1_RATE_CH1=4, R2_RATE=5, R1_RATE_CH1=6, R2_RATE_CH1=4, R2_RATE_CH1=6), ADS1293EVM seemed to read data in normal speed.
In detail, it took almost accurate 60 sec for data read with Capture Mode: Acquire for 60 sec.
.
However, when I changed the digital filter setting (R1_RATE_CH1=4, R2_RATE=8, R1_RATE_CH1=16, R2_RATE_CH1=4, R2_RATE_CH1=128), ADS1293EVM red data abnormally fast.
It took just about 40 sec for data read with Capture Mode: Acquire for 60 sec.
.
What's the problem in this case? What registers should I reconfigurate to make the module to work normally?

In addition, I found sometimes the whole acquired data do not displayed but the last 1 or 2 sec of data when I run the EVM with Capture Mode: Acquire, so that I cannot save them.
It seems to be depend on the digital filter register setting. Do you have any idea in this situation?
.
Thank you,
