[bit5:4] LBL[1:0]: LIN synch break length select bits
These bits select the bit length for the LIN synch break generation time.
The LIN synch break length for reception is always 11 bits.

Writing "11"
[bit3] SOPE: Serial output pin direct access enable bit*
This bit enables or disables direct writing to the SOT pin.
Setting this bit to "1" when serial data output has been enabled (SMR:SOE = 1) enables direct writing to the
SOT pin.
bit3
Writing "0"
Writing "1"
[bit2] SIOP: Serial I.O pin direct access bit*
This bit controls direct access to the serial I/O pin.
The SIOP bit always returns the value of the SIN pin if read by a normal read instruction.
If direct access to the serial output pin is enabled (SOPE = 1), the value written to this bit is reflected in the
SOT pin.

Writing "0"
Writing "1"
Note: When the bit manipulation instruction is used, the SIOP bit returns the bit value of the SOT pin in the
read cycle.

Disables serial output pin direct access.
Enables serial output pin direct access.
Reads the value of the SIN pin.
Has no effect on operation.
Fixes the SOT pin at "0".
Fixes the SOT pin at "1".
Write access to SIOP
It has no effect on operation. (However, the
value written to the SIOP bit is held.)
It writes "0" or "1" to the SOT pin.
It reads the value of the SOT pin and writes "0" or "1" to the SOT pin.
