I don't think you can set those bits, it looks like they are reserved by the hardware here.
Why do you need to set those ?

When I run the Extented Remote Frame and DLC is 0, I hope to set r1 & r0 to needn't [1] bit stuff. If I set r0 'recessive' , and DLC is 0 , there isn't
[1] bit stuff.

Why do you want to play there ?,
R0,R1, are 'Firmware bits that are used to drive the canbus.

I find a solution to this issue. Don't care the r1 or r0 value.
When I run the Extented Remote Frame, I set the DLC is [1111], and there isn't [1] bit stuff on the bit stream waveform.

Without the line drivers, I found the CanRxpin needed a pullup, or the hardware would hang on startup.
Can you receive a frame ?
Do you have a know good transmitter on a bus ?
Best to use a dongle to transmit a known good frame first, then you work on your receiver first.
