10.4.1 Outline of TIO
TIO (Timer Input/Output) is an input/output-related 16-bit timer, whose operation mode can be
selected from the following by mode switching in software:
<Input mode>
• Measure clear input mode
• Measure free-run input mode
• Noise processing input mode
<Output mode without correction function>
• PWM output mode
• Single-shot output mode
• Delayed single-shot output mode
• Continuous output mode
The following shows TIO specifications. Figure 10.4.1 shows a TIO block diagram.
