I found the ADS1256 datasheet terminal table and built non-overlapping groups: power supplies, grounds, reference inputs, analog inputs, control inputs, SPI, oscillator/clock, and digital GPIO.

Grouped the ADS1256IDBT pins from the TI datasheet and updated each terminal with a single non-overlapping Pin Group, plus corrected Pin Type and Pin Description.

Applied groups:

Verified all 28 pins now have exactly one functional group; no pin was duplicated across groups.

I’ll simplify the pin groups to broader categories while keeping each pin in only one group, then verify the update.

Updated the ADS1256IDBT pin groups to broader functional categories with no duplicates:

Verified all 28 terminals now use these general groups while keeping their individual pin descriptions intact.
