CHAPTER 14 LIN-UART
14.7 Registers
Note:
The LIN-UART transmit data register is a write-only register; the receive data register is a
read-only register. Since both registers are located at the same address, the write value
and the read value are different. Thus, the read-modify-write (RMW) type of instruction,
such as the INC instruction and the DEC instruction, cannot be used.
