14.1 Functions of Serial Interface UART6
(1) Operation stop mode
(2) Asynchronous serial interface (UART) mode
290
Serial interface UART6 has the following two modes.
This mode is used when serial communication is not executed and can enable a reduction in the power
consumption.
For details, see 14.4.1 Operation stop mode.
This mode supports the LIN (Local Interconnect Network)-bus. The functions of this mode are outlined below.
For details, see 14.4.2
generator.
Cautions 1. The T
Two-pin configuration
Data length of communication data can be selected from 7 or 8 bits.
Dedicated internal 8-bit baud rate generator allowing any baud rate to be set
Transmission and reception can be performed independently.
Twelve operating clock inputs selectable
MSB- or LSB-first communication selectable
Inverted transmission operation
Synchronous break field transmission from 13 to 20 bits
More than 11 bits can be identified for synchronous break field reception (SBF reception flag provided).
2. If clock supply to serial interface UART6 is not stopped (e.g., in the HALT mode), normal
3. If data is continuously transmitted, the communication timing from the stop bit to the next
side. To use this function, the reception side must be ready for reception of inverted data.
operation continues. If clock supply to serial interface UART6 is stopped (e.g., in the STOP
mode), each register stops operating, and holds the value immediately before clock supply
was stopped. The T
stopped and outputs it. However, the operation is not guaranteed after clock supply is
resumed. Therefore, reset the circuit so that POWER6 = 0, RXE6 = 0, and TXE6 = 0.
start bit is extended two operating clocks of the macro. However, this does not affect the
result of communication because the reception side initializes the timing when it has
detected a start bit. Do not use the continuous transmission function if UART6 is used in
the LIN communication operation.
