https://community.nxp.com/t5/S32K/An-issue-regarding-slave-bit-errors-in-LPI2C/m-p/2385614#M59478 <P>I am using S32K146, and the manual states that a bit error will be triggered when the slave sends 1 but the bus is 0. However, in actual testing, a bit error will also be triggered when the slave sends 0 but the bus is 1. I want to know if this phenomenon is correct?</P> Wed, 24 Jun 2026 08:37:14 GMT GXY 2026-06-24T08:37:14Z https://community.nxp.com/t5/S32K/An-issue-regarding-slave-bit-errors-in-LPI2C/m-p/2385614#M59478 <P>I am using S32K146, and the manual states that a bit error will be triggered when the slave sends 1 but the bus is 0.

Bit error flag is triggered once&nbsp;slave is driving SDA, but samples different<BR />value than what is expected, not necessarily only when it sends 1 and reads 0.</P> <P>My guess is that the register description is simply stating an example for when the bit error flag is set.</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Julin_AragnM_0-1782338806510.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/390055iEDAFCCE736A5E421/image-size/medium?v=v2&amp;px=400" role="button" title="Julin_AragnM_0-1782338806510.png" alt="Julin_AragnM_0-1782338806510.png" /></span></P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Julin_AragnM_1-1782338836158.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/390056iB6C9D2259AD264D6/image-size/medium?v=v2&amp;px=400" role="button" title="Julin_AragnM_1-1782338836158.png" alt="Julin_AragnM_1-1782338836158.png" /></span></P> <P>Best regards,<BR />Julián</P> Wed, 24 Jun 2026 22:07:36 GMT https://community.nxp.com/t5/S32K/An-issue-regarding-slave-bit-errors-in-LPI2C/m-p/2386010#M59490 Julián_AragónM 2026-06-24T22:07:36Z
