Caution The following rules apply when using multiple channels simultaneously.
6.1.3 LIN-bus supporting function
LIN-bus communication format.
Remark For details about setting up the operations used to implement the LIN-bus, see 6.3 (24) Input switch

Chanel 7 of Timer array unit TAUS is used to check whether signals received in LIN-bus communication match the
(1) Detection of wakeup signal
(2) Detection of sync break field
(3) Measurement of pulse width of sync field
Note Timer channel 7 can be used for the LIN-bus function in all products of the 78K0R/Ix3.
The timer starts counting at the falling edge of a signal input to the serial data input pin (RxD0) of UART0 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 (RxD0) of UART0 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 (RxD0) of UART0 are measured. From the bit interval of the sync field measured in this way, a
baud rate is calculated.
• Only an even-numbered channel (channel 0, 2, 4, …) can be specified as the master channel.
• Only channels with lower channel numbers than the master channel can be specified as slave

Simultaneous Channel Operation Function.

channels (multiple slave channels can be set).
Also, when RxD0 functions alternately as a timer input pin, the corresponding timer input pin channels can
also be used for the LIN-bus function. The timer channels in each product of the 78K0R/Ix3 that can be
used for the LIN-bus function in addition to timer channel 7 are shown below.
