Table 29-40. LIN Compare Register (LINCOMPARE) Field Descriptions
Bit Field Value Description
31-19 Reserved 0 Reads return 0. Writes have no effect.
18-16 SDEL 2-bit synch delimiter compare. These bits are effective in LIN mode only. These bits are used to
configure the number of T
bit
for the synch delimiter in the synch field. The default value is 0.
The formula to program the value (in T
bits
) for the synchronization delimiter is:
T
SDEL
= (SDEL + 1) T
bit
0 The synch delimiter has 1 T
bit
.
1h The synch delimiter has 2 T
bit
.
2h The synch delimiter has 3 T
bit
.
3h The synch delimiter has 4 T
bit
.
15-3 Reserved 0 Reads return 0. Writes have no effect.
2-0 SBREAK Synch break extend. These bits are effective in LIN mode only. These bits are used to configure the
number of T
bit
for the synch break to extend the minimum 13 T
bit
break field to a maximum of 20 T
bit
long.
Note: The default value is 0, which adds nothing to the automatically generated SYNCH BREAK.
The formula to program the value (in T
bits
) for the SYNCH BREAK is:
T
SYNBRK
= 13T
bit
+ (SBREAK × T
bit
)
0 The synch break has no additional T
bit
.
1h The synch break has 1 additional T
bit
.
2h The synch break has 2 additional T
bit
.
3h The synch break has 3 additional T
bit
.
4h The synch break has 4 additional T
bit
.
5h The synch break has 5 additional T
bit
.
6h The synch break has 6 additional T
bit
.
7h The synch break has 7 additional T
bit
.
