Bit 6
SUM
: Summary byte
1 = The last valid value from
SUMMARY
was not zero. The importance of this flag
depends on the particular error source that leads to a set
SUMMARY
(see
0 = The last valid value from
SUMMARY
was zero.
Bit 5
SCE:
CRC error on the Safe Channel
1 = The last Safe Channel CRC received was wrong. It is expected that the last safe
position transmitted (see
) is invalid.
0 = The last Safe Channel CRC received was correct.
Bit 4
FIX1
: This bit always gives a "1". For SPI interfaces, this is used for checking the
spi_miso
pin for stuck-at- '0' faults.
Bit 3
POS
: Estimator turned on (functionality based on
estimator_on
, see
)
1 = A source of an error in the fast position was identified or an alignment procedure is
currently being carried out. It is probable that the last fast position is invalid. Be aware
that the fast position read through drive interface is provided by the estimator.
0 = No fast position error.
Bit 2
VPOS
: Safe position invalid
1 = An error in the safe position was identified. It is expected that the safe position
transmitted from the encoder is invalid.
0 = The last safe position received was correct.
Bit 1
DTE
: Deviation Threshold Error (see
)
1 = Current value of deviation greater than the specified maximum.
0 = Current value of deviation smaller than the specified maximum.
Bit 0
PRST
: Protocol reset
1 = IP-Core has restarted the protocol.
0 = IP-Core running.

POSTX1:POSTX0
: Position transmission status
00: Position request is transmitted to the DSL encoder.
01: Safe Channel was correctly transmitted.
10: Fast position present (see
11: Safe Channel 2 was correctly transmitted.
Recommended to trigger on rising edge of a POSTX bit change (is set). A new state is
indicated by a set bit. It is cleared/maintained until a new frame/event arrives.
Bit 5
MIN
: Acknowledgment of message initialization
1 = The DSL encoder sends a figure by which the initialization of the Parameter Chan‐
nel is acknowledged.
0 = Parameter Channel not functioning.
Bit 4
ANS
: Incorrect answer detected.
