Bit Symbol Bit Name Function R/W
0 UEBE Expansion Bit Enable 0: Disables expansion bit operation.
1: Enables expansion bit operation.
R/W
1 UEBDL Expansion Bit Detection Level
Select
0: Selects expansion bit value 0 as the expansion bit detection
level.
1: Selects expansion bit value 1 as the expansion bit detection
level.
R/W
2 UEBDCE Expansion Bit/Data Comparison
Enable
0: Disables data comparison after detection of the expansion
bit.
1: Enables data comparison after detection of the expansion
bit.
R/W
3 UTIGTS Transmission Interrupt Generation
Timing Select
0: Transmission interrupt is generated at the start of
transmission.
1: Transmission interrupt is generated at the completion of
transmission.
R/W
4 UECD Expansion Bit Comparison Disable 0: Enables comparison between the received expansion bit and
the UEBDL bit value.
1: Disables comparison between the received expansion bit
and the UEBDL bit value.
R/W
7 to 5 — Reserved These bits are always read as 0. The write value should always
be 0.
R/W
UEBE bit (expansion bit enable bit)
The UEBE bit enables or disables expansion bit operation.
With 0 set, expansion bit operation is disabled.
With 1 set, expansion bit operation is enabled.
Set this bit when the OMM0 bit in the LMSTn register is 0 (LIN reset mode).
Do not set this bit to 1 when the UART buffer is in use.
UEBDL bit (expansion bit detection level select bit)
The UEBDL bit sets the level to be detected as the expansion bit when the UEBE bit is 1 (expansion bit operation is enabled)
and the UECD bit is 0 (comparison of the expansion bit is enabled).
With 0 set, expansion bit value 0 is the level to be detected as the expansion bit.
With 1 set, expansion bit value 1 is the level to be detected as the expansion bit.
Set this bit when the OMM0 bit in the LMSTn register is 0 (LIN reset mode).
Do not set this bit to 1 when the UART buffer is in use.
