(22) UART Operation Enable Register (LUOERn)
Address: F06E0H

— — — — — — UROE UTOE
Value after reset:
0 0 0 0 0 0 0 0
Bit Symbol Bit Name Function R/W
0 UTOE Transmission Enable 0: Disables transmission.
1: Enables transmission.
R/W
1 UROE Reception Enable 0: Disables reception.
1: Enables reception.
R/W
7 to 2 — Reserved These bits are always read as 0. The write value should always
be 0.
R/W
The LUOERn register is automatically cleared to 00H upon transition to LIN reset mode.
In LIN reset mode, writing to this register is disabled. In LIN reset mode, the register retains 00H.
UTOE bit (transmission enable bit)
The UTOE bit enables or disables transmission.
With 0 set, transmission is disabled.
With 1 set, transmission is enabled.
Do not clear this bit during transmission. To cancel transfer while transmission is in progress, place the module in the LIN
reset mode by setting the OM0 bit in the LCUCn register to 0 (LIN reset mode). Note that this operation also cancels
reception.
UROE bit (reception enable bit)
The UROE bit enables or disables reception.
With 0 set, reception is disabled.
With 1 set, reception is enabled.
Do not clear this bit during reception. To cancel transfer while reception is in progress, place the module in the LIN reset
mode by setting the OM0 bit in the LCUCn register to 0 (LIN reset mode). Note that this operation also cancels
transmission.
This bit must be 0 during transmitting data from UART buffer.
