10.8 TOU (Output-Related 24-Bit Timer)
10.8.1 Outline of TOU
TOU (Timer Output Unification) is an output-related 24-bit timer, whose operation mode can be selected from
the following by mode switching in software, one at a time.
<Output modes without correction function>
• PWM output mode
• Single-shot PWM output mode
• Delayed single-shot output mode
• Single-shot output mode
• Continuous output mode
The table below shows specifications of TOU. The diagram in the next page shows a block diagram of TOU.
Table 10.8.1 Specifications of TOU (Output-Related 24-Bit Timer)
Item Specification
Number of channels 24 channels (8 channels × 3 circuit blocks)
Counter 24-bit down-counter (or 16-bit down counter when in PWM output or single-shot
PWM output mode)
Reload register 24-bit reload register (or 16-bit reload register when in PWM output or single-shot
PWM output mode)
Timer startup TOU0:
• Writing to the enable bit in software
• TID0 underflow/overflow signal
• TOU0_7 underflow signal
• Output event bus 0 signal
• External input TIN25 signal
TOU1:
• Writing to the enable bit in software
• TID1 underflow/overflow signal
• TOU1_7 underflow signal
• TOU0 cause of start signal (Event enable must be selected by TOU0)
• External input TIN27 signal
TOU2:
• Writing to the enable bit in software
• TID2 underflow/overflow signal
• TOU2_7 underflow signal
• TOU0 cause of start signal (Event enable must be selected by TOU0)
• External input TIN29 signal
Mode switching <Output modes without correction function>
• PWM output mode
• Single-shot PWM output mode
• Delayed single-shot output mode
• Single-shot output mode
• Continuous output mode
Interrupt request generation Can be generated by a counter underflow
