8.1.3 LIN-bus supporting function (channel 7 only)

Timer array unit 0 is used to check whether signals received in LIN-bus communication match the LIN-bus
(1) Detection of wakeup signal
(2) Detection of sync break field
(3) Measurement of pulse width of sync field
Remarks 1. The UART channel used for LIN-bus communication differs as follows depending on the product.
The timer starts counting at the falling edge of a signal input to the serial data input pin (RxDk) of UARTk and the
count value of the timer is captured at the rising edge. In this way, a low-level width can be measured. If the low-
level width is greater than a specific value, it is recognized as a wakeup signal.
The timer starts counting at the falling edge of a signal input to the serial data input pin (RxDk) of UARTk after a
wakeup signal is detected, and the count value of the timer is captured at the rising edge. In this way, a low-level
width is measured. If the low-level width is greater than a specific value, it is recognized as a sync break field.
After a sync break field is detected, the low-level width and high-level width of the signal input to the serial data
input pin (RxDk) of UARTk are measured. From the bit interval of the sync field measured in this way, a baud rate
is calculated.
2. For details about setting up the operations used to implement the LIN-bus, see 8.3 (13) Input switch
control register (ISC) and 8.7.5 Operation as input signal high-/low-level width measurement.
