1
DATA
DO
DATA
Output of the SSI.
If PD/CS=0, the measured angle data (6bit value) is serially
shifted out over this pin by the CLK, starting with the MSB. A
NVR Bit and a Parity bit are added. (NVR=1 indicates a
N

R
ange of the magnetic field.) Even Parity is given.

Positive Supply Voltage.
3

ramming Input.
This pin is used to program the zero position into a non-volatile
memory (OTP). The programmed value is subtracted from the
actual measured angle.

PD/CS=0 activates the device and enables the measurement.
PD/CS=1 sets the device in power save mode and puts the
DATA pin in high impedance (highZ) state.

K
Input of the SSI.
This pin is used to serially clock out the measured angle data at
Pin 7 (DATA).

Analogue Input
OTP: One Time Programmable
DI: Digital Input
DO: Digital Output
MSB: Most Significant Bit
LSB: Least Significant Bit
Note: The pins 5 and 6 must not be connected!
