16-bit timers. Each 16-bit timer is called a channel and can be used as an independent timer. In addition, two or more
“channels” can be used to create a high-accuracy timer.
of serial array unit 1.
7.1 Functions of Timer Array Unit
7.1.1 Functions of each channel when it operates independently
of the other channel (for details, refer to 7.6.1 Overview of single-operation function and combination-operation
function).

The timer array unit has two units. The timer array unit 0 has eight 16-bit timers and the timer array unit 1 has four
Channel 7 of the timer array unit 0 can be used to realize LIN-bus reception processing in combination with UART3
The timer array unit has the following functions.
Single-operation functions are those functions that can be used for any channel regardless of the operation mode
(1) Interval timer
(2) Square wave output
(3) External event counter
(4) Divider function (channel 0 of unit 0 only)
(5) Input pulse interval measurement
Each timer of a unit can be used as a reference timer that generates an interrupt (INTTMmn) at fixed intervals.
A toggle operation is performed each time INTTMmn is generated and a square wave with a duty factor of
50% is output from a timer output pin (TOmn).
Each timer of a unit can be used as an event counter that generates an interrupt when the number of the valid
edges of a signal input to the timer input pin (TImn) has reached a specific value.
A clock input from a timer input pin (TI00) is divided and output from an output pin (TO00).
Counting is started by the valid edge of a pulse signal input to a timer input pin (TImn). The count value of the
timer is captured at the valid edge of the next pulse. In this way, the interval of the input pulse can be
measured.
