Hello the community,
I am working on NXP S32K146 µc and S32DS IDE.
I have an issue on SPI with chip select management. The µc is configured in master, and it communicates with 2 slaves on CS0 and CS3.
Firstly, the µc communicate on CS0 --> OK
Secondly, the µc communicate on CS3 --> OK
But if :
Firstly, the µc communicate on CS3 --> OK
Secondly, the µc communicate on CS0 --> NOK
I check the register TCR (bits PCS) when I active both CSx and everything is ok. But when I have checked on scope, I saw, as soon as CS3 is selected, the pin CS3 stays activated and never CS0.
My question is, what I have to do when I want to change the CS, the register TCR (PCS) is not enought ? (Of course the CS is not changed during transfert)
Thanks by advance
