(3) TAU initialization
<Channel 1 setting conditions>
 Operating clock: middle-speed on-chip oscillator (MOCO) 4MHz
 Use 16-bit timers
 Software trigger start
 MOCO valid edge: falling edge
 Interval timer mode/square waveform output
 Timer interrupt is not generated when count starts.
 Positive logic output
<Channel 3 setting condition>
 Operating clock: high-speed on-chip oscillator (HOCO) 24MHz
 Use 16-bit timers
 TI03 pin valid edge: set to start trigger and capture trigger
 TI03 pin valid edge: rising edge
 Input pulse width measurement mode
 Positive logic output
(4) Interrupt initialization
<Setting conditions>
 Pin input edge detection (INTP11): rising edge
