6.1 Functions of Timer Array Unit TAUS
6.1.1 Independent channel operation function
operation mode of other channels.
268
Timer array unit TAUS has the following functions.
By operating a channel independently, it can be used for the following purposes without being affected by the
(1) Interval timer
(2) Square wave output
(3) External event counter
(4) Divider function (48-pin products of 78K0R/IC3, 78K0R/ID3, and 78K0R/IE3 only)
(5) Input pulse interval measurement
Remarks 1. n = 00, 02 to 11, m = 00, 10, 11
Each timer of a unit can be used as a reference timer that generates an interrupt (INTTMn) at fixed intervals.
A toggle operation is performed each time INTTMn is generated and a square wave with a duty factor of 50%
is output from a timer output pin (TOn, 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 (TIn, SLTI) has reached a specific value.
A clock input from a timer input pin (TIm) is divided and output from an output pin (TOm).
Counting is started by the valid edge of a pulse signal input to a timer input pin (TIn, 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.
2. The presence or absence of timer I/O pins of Channel 0, 1 and 8 to 11 in each timer array unit channel
depends on the product. see Table 6-1 Timer I/O Pins provided in Each Product for details.
