R/W Description
R/W Start
When the FRC bit in TWCR1 is 0 and 1 is written to this
bit, duty measurement will start. If this bit is read during
duty measurement, 1 is read from this bit. If duty
measurement ends, this bit is automatically cleared to 0.
If 0 is written during duty measurement, duty
measurement forcibly ends. Even if 1 is written when the
FRC bit in TWCR1 is 1, it is ignored.
