eSCI Data Register (ESCI
x
_DR)
6
BRK13
Break transmit character length. Determines whether the transmit break character is either 10 or 11, or 13 or 14 bits
long. The detection of a framing error is not affected by this bit.
0
Break Character is 10 or 11 bits long
1
Break character is 13 or 14 bits long
Note:
LIN 2.0 now requires that a break character is always 13 bits long, always set this bit to 1. The eSCI works
with BRK13=0, but it violates LIN 2.0.
7
Reserved. This bit is readable/writable, but has no effect on the operation of the eSCI module.
8
BESM13
Bit error sample mode, bit 13. Determines when to sample the incoming bit to detect a bit error. This only applies
when FBR is set.
0 Sample at RT clock 9
1 Sample at RT clock 13 (Refer to
Section 21.4.5.3, “Data Sampling
9
SBSTP
SCI bit error stop. Stops the SCI when a bit error is asserted. This allows to stop driving the LIN bus quickly after a
bit error has been detected.
0 Byte is completely transmitted
1 Byte is partially transmitted
10–11
Reserved.
12
ORIE
Overrun error interrupt enable. Generates an interrupt, when a frame error is detected. For a list of interrupt enables
and flags, Refer to
13
NFIE
Noise flag interrupt enable. Generates an interrupt, when noise flag is set. For a list of interrupt enables and flags,
Refer to
14
FEIE
Frame error interrupt enable. Generates an interrupt, when a frame error is detected. For a list of interrupt enables
and flags, Refer to
15
PFIE
Parity flag interrupt enable. Generates an interrupt, when parity flag is set. For a list of interrupt enables and flags,
