Figure 7. 2-Wire SSI Read-only Mode
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 AS5134
angular data is invalid, the PWM output will remain at low state. Pins that are not shown may be left open.
