4.18 1-Wire PWM Connection
This configuration uses the least number of wires: only one line
(PWM) is used for data, leaving the total number of connection
to three, including the supply lines. This type of configuration
is especially useful for remote sensors.
Ultra Low Power Mode is not possible in this configuration, as
there is no bi-directional data transmission.
If the AS5030 angular data is invalid, the PWM output will
remain at low state. Pins that are not shown may be left open.
Note that the PWM output is invalid when the AGC is disabled
(see 5.2.2).
Figure 13: Data transmission with pulse width modulated (PWM) output
The minimum PWM pulse width tON (PWM = high) is 1 LSB @ 0° (Angle reading = 00H).
1LSB = nom. 2.26µs.
The PWM pulse width increases with 1LSB per step. At the maximum angle 358.6° (Angle reading = FFH),
the pulse width tON (PWM = high) is 256 LSB and the pause width tOFF (PWM = low) is 1 LSB.
This leads to a total period (tON + tOFF) of 257LSB.

This means that the PWM pulse width is (position + 1) LSB, where position is 0….255.
The tolerance of the absolute pulse width and -frequency can be eliminated by calculating the angle with the duty cycle rather
than with the absolute pulse width:

Note: the absolute frequency tolerance is eliminated by dividing tON by (tON+TOFF), as the change of the absolute timing effects
both TON and TOFF in the same way.
