ADS1256 sample value error

[hustlong]

I use ads1256 bcm python3 on rasperry4b, with 15000SPS and read data continuous mode.
使用树莓派4b python3 bcm模式， 15k采样率，连续读模式。

there appear some error voltage value sometimes.
经常会出现一些毛刺错误结果。

so，what is the reason? it is because the board or my program?
所以，到底是什么原因呢，是电路板自身的原因，还是我的程序有问题？

These spikes indicate an incorrect value of the MSB, so they can be due to incorrect t6 and/or t11 delay (see ADS1256 datasheet).
