SPI how to send three data in one cs with MCAL?

[Alex_min]

Hello, here is my SPI configuration. I can send twenty data in one CS, but i can't send three data in one CS, why?

I try to modify SpiEbMaxLength to three, but can't send out data.

Hi @Alex_min 

For better support, could you please specify which MCU, IDE and SDK you are using?

S32K144 in the S32 Design Studio for S32 Platform 3.5. Use the S32K1 RTD AUTOSAR 4.4 Version   1.0.1 package.@VaneB

Could you please check if any status register flag is set?
Also, have you tried assigning a value greater or less than 3 (ex.4,1) in SpiEbMaxLength?
