Hello,

can you confirm that the description for comm mode on page 1393 of SPNU499a (nov 2012) and on page 1456 is wrong.

Idle-line mode is selected by 0 and address-bit mode is selected by 1, correct ?

Tristian,

Your observation is correct. please refer to the correct description below

Bit 0 COMM MODE SCI communication mode bit. Selects the SCI communication mode.

0 = Idle-line mode

1 = Address-bit mode

We will make an update to the TRM

Hello,

Is this true for the corresponding definition in the SCI/LIN Control Registers on page 1393 (SPNU499b)? The two definitions now contradict each other.

Thanks, Charlie Johnston

Hello Charles,

I just requested change to the SPNU499b in this regard. It should be:

SCI mode:

0: Idle-line mode

1: Address-bit mode

LIN mode:

0: ID4 and ID5 are not used for length control

1: ID4 and ID5 are used for length control

Thanks, Charles.

I can't mark this as the correct answer since I didn't start the thread.
