Value Description
Receive data in. .
This bit is effective in LIN or SCI-compatible mode. This bit contains the current value on the
SCIRX pin
0 The SCIRX pin is at logic low (0).
1 The SCIRX pin is at logic high (1).
Reads return zero and writes have no effect.

Value Description
Reads return zero and writes have no effect.
2-bit synch delimiter compare.
These bits are effective in LIN mode only. These bits are used to configure the number of T
the synch delimiter in the synch field.
The time delay value for the synchronization delimiter is
T = (SDEL + 1)T
SDEL bit
0h The synch delimiter has 1 T
1h The synch delimiter has 2 T
2h The synch delimiter has 3 T
3h The synch delimiter has 4 T
Reads return zero and writes have no effect.
