7.1.2 Functions of each channel when it operates with another channel
reference timer that controls cycles) and the slave channels (timers that operate following the master channel) in
combination (for details, refer to 7.6.1 Overview of single-operation function and combination-operation
function).
7.1.3 LIN-bus supporting function (channel 7 only)
(6) Measurement of high-/low-level width of input signal
Combination-operation functions are those functions that are attained by using the master channel (mostly the
(1) PWM (Pulse Width Modulator) output
(2) One-shot pulse output
(3) Multiple PWM (Pulse Width Modulator) output
(1) Detection of wakeup signal
(2) Detection of sync break field
(3) Measurement of pulse width of sync field
Remark
Counting is started by a single edge of the signal input to the timer input pin (TImn), and the count value is
captured at the other edge. In this way, the high-level or low-level width of the input signal can be measured.
Two channels are used as a set to generate a pulse with a specified period and a specified duty factor.
Two channels are used as a set to generate a one-shot pulse with a specified delay time and a specified pulse
width.
By extending the PWM function and using one master channel and two or more slave channels, up to seven
types of PWM signals that have a specific period and a specified duty factor can be generated.
The timer starts counting at the falling edge of a signal input to the serial data input pin (RxD3) of UART3 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 (RxD3) of UART3 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 (RxD3) of UART3 are measured. From the bit interval of the sync field measured in this way, a
baud rate is calculated.
