TIO4M

000: Single-shot output mode

TIO4 operation mode select bit

001: Delayed single-shot output mode

010: Continuous output mode

011: PWM output mode

100: Measure clear input mode

101: Measure free-run input mode

110: Noise processing input mode

111: Noise processing input mode

Note 1: During measure free-run/clear input mode, even if this bit is set to "0" (external input disabled), when a capture signal is

entered from an external device, the counter value at that point in time is written into the measure register. In measure clear

input mode, however, if this bit = "0" (external input disabled), the counter value is not initialized (H’FFFF) upon capture and,

therefore, this bit should be set to "1" (external input enabled) when using measure clear input mode.

Note: • Operation mode can only be set or changed while the counter is inactive.
