3.7. PWM / 1-WIRE

Pin	Signal	Description						type	I/O
42	PWM	Pulse-Width Modulator (PWM) Output						VDDIO	O
		Module			Remark
		TX51			Be aware of the voltag level on this pin: 3.1V instead of 1.8V
43	OWIRE	1-Wire						VDDIO	I/O
		Module			Remark
		TX28/TX48/TX6			No 1-Wire controller - a GPIO is used instead

1-Wire is a registered trademark of Dallas Semiconductor for a device communications bus systems designed by Dallas Semiconductor that provides low-speed data, signalling and power over a single signal, albeit using two wires, one for ground, one for power and data. 1-Wire is similar in concept to I2C, but with lower data rates and longer range. It is typically used to communicate with small inexpensive devices.
