Bit 12—Output Terminal Select (OTS): Bit 12 selects the pin used for PWM output according
to the value in bit 12 in the buffer register that is transferred by a PWCYR1 compare match.
Unselected pins output a low level (or a high level when the corresponding bit in PWPR1 is set to
1).

Bits 11 and 10—Reserved: These bits cannot be read from or written to.
Bits 9 to 0—Duty (DT): Bits 9 to 0 set the PWM output duty according to the values in bits 9 to 0
in the buffer register that is transferred by a PWCYR1 compare match. A high level (or a low level
when the corresponding bit in PWPR1 is set to 1) is output from the time PWCNT1 is cleared by a
PWCYR1 compare match until a PWDTR1 compare match occurs. When all the bits are 0, there
is no high-level output period (no low-level output period when the corresponding bit in PWPR1
is set to 1).
