Specification

Data Sheet

Rev. 2.0, 2014-02

In parallel to SPC, the SSC interface can be used for individual configuration. The number of transmitted SPC

nibbles can be changed to customize the amount of information sent by the sensor. The frame contains a 16-bit

angle value and an 8-bit temperature value in the full configuration (Table 4-19).

Sensors with preset SPC are available as TLE5012B E9000

The status nibble, which is sent with each SPC data frame, provides an error indication similar to the Safety Word

of the SSC protocol. In case the sensor detects an error, the corresponding error bit in the Status register is set

and either the bit SYS_ERR or the bit ELEC_ERR of the status nibble will be “high”, depending on the kind of error

(see Table 4-20). Except for an S_ADCT error, an error is only indicated by the corresponding error bit in the

status nibble as long as it persists, but at least once. However the value in the status register will remain until a

read-out via the SSC interface or a chip reset is performed. An S_ADCT error on the other side will be transmitted

until the next chip reset. The fail-safe diagnostic function can be disabled via the MOD_4 register.

Unit Time Setup

The basic SPC protocol unit time granularity is defined as 3

μs. Every timing is a multiple of this basic time unit.To

achieve more flexibility, trimming of the unit time can be done within IFAB_HYST. This enables a setup of different

unit times.
