(3) The products described in this book are intended to be used for standard applications or general electronic equipment
(such as office equipment, communications equipment, measuring ins truments and household appliances).
Consult our sales staff in advance for information on the following applications:
x Special applications (such as for airplanes, aerospace, automobiles, traffic control equipment, combustion equipment,
life support systems and safety devices) in which exceptional quality and reliability are required, or if the failure or
malfunction of the products may directly jeopardize life or harm the human body.
x Any applications other than the standard applications intended.
(4) The products and product specifications described in this book are subject to change without notice for modification and/
or improvement. At the final stage of your de sign, pur chasing, o r use of the p roducts, therefore , ask for the mo st up-todate Product Standards in advance to make sure that the latest specifications satisfy your requirements.

tions (operating power supply voltage and operating environment etc.). Especially, please be careful not to exceed the
range of absolute maximum rating on the transient state, such as power-on, power-off and mode-switching. Otherwise,

3.9 8-bit Timer, Initializing Peripherals
There are five 8-bit timers comprising timer 0 to 4.
The timer comprises a binary counter, a compare register and a mode register. You can combine two 8-bit timers,
timer 0 and 1 or 2 and 3, to use as a 16-bit timer.
Binary counter
This counter counts a clock selected by the prescaler or the mode register.
Compare register
This register determines the time base of a timer by specifying clock number counted by the binary counter.
Mode register
This register enables/disables the timer operation, and selects the clock source. The setting content of the
mode register depends on the timer.

3.9.1 Types of setting for 8-bit timer
Interval timer
You can apply interval timer setting to all 8-bit timers ranging from the timer 0 to 4. Your source clock
selection and compare register setting determines the generation cycle of the timer interrupt. The timer
generates the interrupt on the next count after it matches the set value on the compare register, then clears
the count. You write a count which is equivalent to a period setting minus 1 to the compare register.
64
The following is the example for setting the interval timer with 10 milli seconds.
To set to the interval timer with 10 milli seconds, convert the time base to the frequency first.
Formula: 1 / 10 milli seconds = 100 Hz
Setting by using
high speed oscillation clock:
The prescaler can set the high speed oscillation clock to 4, 16, 32 or 64 divisions.
Page 13
Chapter 3 Register Setup of Each Function
20 MHz / 64 = 312500 312500 / 100 = 3125
This setting is not available with the 8-bit timer.

Timer pulse output setting
The timer pulse output can provide a pulse signal at an arbitrary frequency.
The period of the timer pulse output is twice as long as the period set on the compare register.
To provide timer pulse, set the output mode register (special register) of the port 1 to the timer output,
and set the input/output setting register to output. See "3.7.2 Port 1".)
The timer setting for timer pulse output setting is identical to that for the inte rval timer.
PWM operation
The PWM output generates the PWM basic component and provides it from the timer output pin when the
binary counter and the compare register of a timer match or on the overflow timing of the binary counter.
Since the PWM output uses the overflow of the binary counter, you can use only the frequency component
generated by the overflow of the timer. The resolution of the PWM output is fixed to the one 255th due to
the 8-bit counter.
The PWM output provides "1" until it counts up to the count set on the compare register after count start
(00), and then provides "0" until it overflows after the match to the compare register.
Since the frequency components use the timer overflow, they are determined by the prescaler setting. This
sample uses the low speed oscillation clock (assuming its oscillation is at 32.768 kHz) to set the 1/4 duty
output for the 128 Hz frequency.

Synchronous output operation
The synchronous output operation provides the output from the port D at the count up timing of the
timer. You can use the timer 1 and 2 for the synchronous output.
You use the port D to set the synchronous output operation. See "3.7.12 Port D".)
You can use the timer setting both in the interval timer mode and event count mode. You can also set
67
Page 16
Chapter 3 Register Setup of Each Function
the interval output for the interval timer.
Serial interface transfer clock generation
You can use the ouput signal from a timer to generate a serial transfer clock.
You can use the interval timer and timer output setting to set the timer.
The following timers are available for the serial interface communication.
Timer 2 Timer 3 Timer 4
Serial 0 Available Not available Available
Serial 1 Not available Not available Available
Serial 2 Not available Available Not available
Serial 3 Not available Available Not available
When you use the timer as transfer clock for the serial interface communication, the transfer speed will be
the half of the setting value.
Declare the setting value in advance because it varies depending on the communication transfer speed.
This sample uses the case when the communication transfer speed is 19200 bps.
See the setting value list of the serial interface transfer speed in the LSI User's Manual for the setting
value.
