Preliminary Technical Data
LIN Frame Data Byte
The data byte frame carries between one and eight bytes of
data. The number of bytes contained in the frame will be
LIN Frame Data Transmission and Reception
Once the Break Symbol and Synchronization Byte have being
correctly received, data is transmitted and received via the
COMTX and COMRX MMRs, after configuration of the UART
to the required Baud Rate. To configure the UART for use with
LIN requires the use of the following UART MMRs:
- COMDIV0: divisor latch (low byte)
- COMDIV1: divisor latch (high byte)
- COMDIV2: 16-bit fractional baud divide register
- COMCON0: line control register
Once the UART is correctly configured, the LIN protocol for
receiving and transmitting data is identical to the UART
specification. To manage data on the LIN bus requires use of
the following UART MMRs:
The required values for COMDIV0, COMDIV1 and
COMDIV2 are derived from the LHSVAL0, to generate the
required baud rate..

dependent on the LIN Master. The data byte frame is split into
data bytes as shown in Figure 43.
BIT4
- COMTX: 8-bit transmit register
- COMRX: 8-bit receive register
- COMCON0: line control register
- COMSTA0: line status register
To transmit data on the LIN bus requires that the relevant data
be placed into COMTX. To read data received on the LIN bus
requires the monitoring of COMRX. To ensure that data is
received or transmitted correctly COMSTA0 is monitored. For
more information please refer to the UART section of the
datasheet.
Under software control it is possible to multiplex the UART
data lines (TxD and RxD) to external GPIO pins (GPIO_7 and
GPIO_8). For more information please refer to the description
of the GPIO Port1 Control Register (GP1CON).
