NOTE
This reserved register is designed for factory test purposes only, and is not
intended for general user access. Writing to this register when in special
mode can alter the module’s functionality.

TxD-dominant timeout disable Bit
— This bit disables the TxD-dominant timeout feature. Disabling this feature
is only recommended for using the LIN Physical Layer for other applications than LIN protocol. It is only writable
in shutdown mode (LPE=0).
0 TxD-dominant timeout feature is enabled.
1 TxD-dominant timeout feature is disabled.

LPSLR[1:0]
Slew-Rate Bits
— Please see section 23.4.2 for details on how the slew rate control works. These bits are only
writable in shutdown mode (LPE=0).
00 Normal Slew Rate (optimized for 20 kbit/s).
01 Slow Slew Rate (optimized for 10.4 kbit/s).
10 Fast Mode Slew Rate (up to 250 kbit/s). This mode is not compliant with the LIN Protocol (LIN electrical
characteristics like duty cycles, reference levels, etc. are not fulfilled). It is only meant to be used for fast data
transmission. Please refer to section 23.4.2.2 for more details on fast mode.Please note that an external
pullup resistor stronger than 1 k
might be necessary for the range 100 kbit/s to 250 kbit/s.
