Requesting for correct timing configuration parameter for I2C

 Using S32K344 EV board for sensor interfacing via I2C channel. Operating frequency is 10 MHZ and I want to operate slave device in standard mode(100KHZ).

currently when I am transmitting data on SDA line but I don't see correct data.

So I think this is the issue with timing configuration, Can you please provide correct I2C timing configuration for above mentioned parameter ?

Hi

Please note the Table 421. LPI2C Timing Parameter Restrictions of S32K3XXRM.

Table 421. LPI2C Timing Parameter Restrictions.pngTable 421. LPI2C Timing Parameter Restrictions.png

DATAVD Maximum CLKLO - SDA_LATENCY - 1. It does not meet.
BUSIDLE Minimum (CLKLO+SETHOLD+2) x 2. It does not meet.
