Is the SAM bit effective in F2806x_ECan.c of example_2806xECanBack2Back project

Hello all

Look at the TI example,in F2806x_ECan.c,we can see ECanaShadow.CANBTC.bit.SAM = 1 but ECanaShadow.CANBTC.bit.BRPREG = 1

According to the 2806X manual The CAN module samples three times and make a majority decision. The triple sample mode
shall be selected only for bit rate prescale values greater than 4 (BRP > 4).

So I want to know whether the SAM bit setting is effective in F2806x_ECan.c of example_2806xECanBack2Back project ?

Chao,

The example code you refer should not be setting the SAM bit. We will have this corrected.

Hello Hareesh

I found the second question:

Look at line 213,218 and 222 of the file "Example_2806xECanBack2Back.c",we can find two "EALLOW" but only one "EDIS" .

Is "EALLOW" on line 218 superfluous? Or we lost a "EDIS"?

EALLOW on line 218 is redundant.
