The 78K0R/Lx3 is provided with two timer array units. Time array unit 0 is provided with eight 16-bit timers and timer
array unit 1 is provided with four 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.
Independent Operation Function
• Interval timer
• Square wave output
• External event counter
• Divider function
• Input pulse interval measurement
• Measurement of high-/low-level width of input signal
Combination Operation Function
• PWM output
• One-shot pulse output
• Multiple PWM output
Channel 7 of timer array unit 0 can be used to realize LIN-bus reception processing in combination with UART3 of serial
array unit 1.
Cautions 1. Channel 5 of timer array unit 0 of the 78K0R/LF3 can be used only as an interval timer.
2. Channel 6 of timer array unit 0 of the 78K0R/LF3 can be used only as an interval timer, for PWM
output (master channel), and for one-shot pulse output (master channel when software trigger
start is selected).
3. Channels 0 to 3 of timer array unit 1 of the 78K0R/LF3 and 78K0R/LG3 can be used only as
interval timers.
4. Channels 1, 5 to 7 of timer array unit 0 and channels 0 to 3 of timer array unit 1 cannot be used as
frequency dividers.
