... AS1506 Data Sheet - Detailed Description The AS1506 contains a resistor array with 255 resistive elements (tap points), and has a total end-to-end resistance of 10, 50, or 100kΩ (see Ordering Information on page The device provides high, low, and wiper terminals for a standard voltage-divider configuration. Pins HIGH, LOW, and WIPER can be connected in any configuration as long as their voltages fall between GND and V A 3-wire, SPI-compatible serial interface controls movement of the wiper among the 256 tap points ...

... Power-Up The AS1506 contains an integrated power-up circuit. At power up, the data are transferred from the non-volatile mem- ory to the wiper register. The wiper register moves to the stored position. This data transfer takes 5µs after the supply has reached the POR trigger level. ...

... With the next falling edge of CSN the SDIO pin is set to an input pin again. Read Wiper Register The AS1506 features the capability to read the data from the wiper register via the SPI interface page 12). This command can be implemented 16-bit command. The SDIO pin is a bi-directional pin. During the CSN low phase of the sequence, the SDIO pin is used as input pin to set the command byte ...
