AWR6843AOP: Question about adding CANFD (MCAN)

Champs,

Below is part of "CAN_Initialize()" of lab0005_object_data_over_can of automotive toolbox.

[Q1] So, "SOC_setPeripheralClock()" and "SOC_initPeripheralRam()" must be called, right?

[Q2] Can you explain about below two register settings? Should they also be included?

    CSL_FINSR(0x43201450, 22, 22, 0x1U);
    CSL_FINSR(0x4320140C, 26, 16, 0x23U);

Thanks & regards,

Hayden
