The timer array unit has eight 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.

channel 6

channel 7

 

 

For details about each function, see the table below. 

Independent channel operation function 

Simultaneous channel operation function 

•  Interval timer (→ see 6.8.1) 
•  Square wave output (→ see 6.8.1) 
•  External event counter (→ see 6.8.2) 
•  Divider

 (

→ see 6.8.3) 

•  Input pulse interval measurement (→ see 6.8.4) 
•  Measurement of high-/low-level width of input signal 
    (

→ see 6.8.5) 

•  Delay counter (→ see 6.8.6) 

•  One-shot pulse output(→ see 6.9.1) 
•  PWM output(→ see 6.9.2) 
•  Multiple PWM output(→ see 6.9.3) 

 
Note  Only channel 0 of unit 0. 

 

It is possible to use the 16-bit timer of channels 1 and 3 of the units 0 as two 8-bit timers (higher and lower).  The 

functions that can use channels 1 and 3 as 8-bit timers are as follows: 

 
•  Interval timer (higher/lower 8-bit timer only)/square wave output (lower 8-bit timer only) 
•  External event counter (lower 8-bit timer only) 
•  Delay counter (lower 8-bit timer only) 

 

Channel 7 of unit 0 can be used to realize LIN-bus communication operating in combination with UART2 of the serial 

array unit (32, 48, and 64-pin products only).
