• Manufacturer Part Number: HD64336901G
• Description: (HD64xxx Series) 16-BIT MICROCONTROLLER
• Manufacturer: Renesas Technology

The timer W has a 16-bit timer having output compare and input capture functions. The timer W
can count external events and output pulses with an arbitrary duty cycle by compare match
between the timer counter and four general registers. Thus, it can be applied to various systems.
12.1
Table 12.1 summarizes the timer W functions, and figure 12.1 shows a block diagram of the timer
W.
TIM08W0A_000020020200
Selection of five counter clock sources: four internal clocks ( , /2, /4, and /8) and an
external clock (external events can be counted)
Capability to process up to four pulse outputs or four pulse inputs
Four general registers:
Four selectable operating modes:
Any initial timer output value can be set
Five interrupt sources
Four compare match/input capture interrupts and an overflow interrupt.
Independently assignable output compare or input capture functions
Usable as two pairs of registers; one register of each pair operates as a buffer for the output
compare or input capture register
Waveform output by compare match
Selections of 0 output, 1 output, or toggle output
Input capture function
Rising edge, falling edge, or both edges
Counter clearing function
Counters can be cleared by compare match
PWM mode
Up to three-phase PWM output can be provided with desired duty ratio.
