Hi @Prerna_Nibe
I suggest you take a look at the Driver User Manual and Integration Manual provided with the RTDs. These documents provide details about the I2S driver (limitations, HW and SW requirements, usage, configurations, etc.) with MCAL. These can be found, for example: C:\NXP\S32DS.3.5\S32DS\software\PlatformSDK_S32K1_S32M24\RTD\I2s_TS_T40D2M20I0R0\doc (S32DS updatesite) or C:\NXP\SW32K1_S32M24x_RTD_4.4_R21-11_2.0.0\eclipse\plugins\I2s_TS_T40D2M20I0R0\doc (file installed by RTD.exe)
