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.
TIMER ARRAY UNIT
16-bit timers
channel 1
channel 0
channel 2
channel 6
channel 7
For details about each function, see the table below.
Independent channel operation function Simultaneous channel operation function
• Interval timer (→ refer to 6.7.1)
• Square wave output (→ refer to 6.7.1)
• External event counter (→ refer to 6.7.2)
• Divider function
Note
(→ refer to 6.7.3)
• Input pulse interval measurement (→ refer to 6.7.4)
• Measurement of high-/low-level width of input signal
(→ refer to 6.7.5)
• Delay counter (→ refer to 6.7.6)
• One-shot pulse output(→ refer to 6.8.1)
• PWM output(→ refer to 6.8.2)
• Multiple PWM output(→ refer to 6.8.3)
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 and 1 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
• 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 (30, 32, 36, 40, 44, 48, 52, 64, 80, 100, and 128-pin products only).
