"Short message" transactions are generated if operations are carried out with remote

registers (DSL Slave). Generally, FRES (in the EVENT_S register) must be set after a

transaction is started. Only then will PC_DATA contain valid information.

8 bit value of the requested remote register.

6.3.24 Fast position error counter

The ACC_ERR_CNT register returns the count of transmitted fast position values with

consecutive transmission errors. The value is clamped to a maximum of 31 (1Fh).

With a writing access the error threshold for the test signal acc_thr_err can be set.

This value is also clamped to a maximum of 31 (1Fh). If the count of transmitted fast

position values with consecutive transmission errors exceeds this threshold

acc_thr_err will be set to ‘1’.

CNT4:CNT0: Position error count/threshold for acc_thr_err

Read: 5 bit value of count of transmitted fast position values with consecutive transmis‐

sion errors

Write: 5 bit value for threshold of acc_thr_err

6.3.25 Fast position acceleration boundary

The MAXACC register allows setting an acceleration threshold for a given application.

This threshold is used by the fast position estimator to clamp the acceleration of the

estimated position during communication or sensor failures of the fast position chan‐

nel.
