Asynchronous Serial Interface C (UARTC)
User’s Manual U16580EE3V1UD00
15.5.2 SBF transmission/reception format
The UARTC has a SBF (Sync Break Field) transmission/reception control function to enable use of the
LIN (Local Interconnect Network) function.
Figure 15-12:
LIN Transmission Manipulation Outline
Notes: 1.
The interval between each field is controlled by software.
2.
SBF output is performed by hardware. The output width is the bit length set by bits
UCnSBL2 to UCnSBL0 of the UCnOPT0 register. If even finer output width adjustments are
required, such adjustments can be performed using bits UCnBRS7 to UCnBRS0 of the
UCnCTLn register.
3.
80H transfer in the 8-bit mode is substituted for the wake-up signal frame.
4.
A transmission enable interrupt (INTUCnT) is output at the start of each transmission. The
INTUCnT signal is also output at the start of each SBF transmission.
