SPC address setting in bus mode
The address of the sensor, so that it responds to a corresponding SPC trigger pulse, has to be set in the
EEPROM. All parts delivered from Infineon have the default address of ID = 0 in the EEPROM. Please refer to
description of EEPROM register 0x00A4 in
The address of the sensor written to the EEPROM must be identical to the address of the sensor defined via
hard-wiring of the pins IF1, IF2 and IFC.

Figure 4 shows a SPC frame with constant trigger length of 90UT, a status nibble, 3 data nibbles, a rolling
counter nibble and a CRC nibble. The low time of the trigger nibble determines the address of the sensor.

EEPROM Description
Register
0x00A2 A short serial message (slow message) can be activated,
which transmits one bit of a 16 bit information in each SPC
frame and thus needs 16 SPC frames for the whole data
transmission.This transmitted information is the
programmed angle base and rotation direction, the chip
temperature and 32 bit of the customer ID.
0x00A2 The SPC unit time (UT) can be selected in the range of 1.0 µs
to 3.0 us.
