"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.

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’.

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.
