LLCE RXOUT FIFO USE

[LeeHua]

HI NXP:

     What does the statement "  The host can configure filters with the receive interface set to one of these 6 FIFOs, which can be shared across all of the channels." mean about RXOUT FIFO in LLCE_firemware_user_guide doucment? How to use the rest of FIFOs(16-21)?

Hi,

Can you let us know which LLCE version are you using? For us to provide information under the same documentation version.

Please, let us know.

 Hello, @Daniel-Aguirre ,

        The LLCE version is " S32G_LLCE_1_0_5_QLP1".

Hi,

For the available information, we understand that these 6 FIFO's are meant for internal functionality of the LLCE. The following is told under the LLCE FW User Guide [Page 21, v1.0.5QLP1]:

"The logging interface transfers RX descriptors from LLCE to Host (RXOUT(17)) and from Host to LLCE (RXOUT(16))."

Which are 2 of the RXOUT FIFO locations you are mentioning. On regards of the other 4, we are not seeing much information, but we assume they are also being used for internal features.

Please, let us know.
