PWM mode 2.
TIOR will not initialize the buffer register pins. If initialization is required, clear buffer mode,
carry out initialization, then set buffer mode again.

perform initialization with TIOR, then restore TIOR to its initial value, and temporarily disable
channel 3 and 4 output with the timer output master enable register (TOER). Then operate the
unit in accordance with the mode setting procedure (TOCR setting, TMDR setting, TOER
setting).
