8.1 Functions of Timer Array Unit
8.1.1 Independent channel operation function
mode of other channels.

Timer array unit has the following functions.
By operating a channel independently, it can be used for the following purposes without being affected by the operation
(1) Interval timer
(2) Square wave output
(3) External event counter
(4) Divider function
(5) Input pulse interval measurement
(Note, Caution, and Remark are listed on the next page.)
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 interrupt is generated and a square wave with a duty factor of
50% is output from a timer output pin (TOmn, SLTO).
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, SLTI) 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, SLTI). 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.
