Keywords:microcontroller? MCU? timer array unit?

The 78K0R 16bit MCU family introduces a new timer structure for the classical timing applications. The timer array unit is composed of eight 16bit timers. Each 16bit 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.

The following timing functions can be realized with the different channels:

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 the TAU also has an alternative role: it can be used to realize LIN bus reception processing in combination with UART3 of serial array unit 1.
