The execution control flags provide information about the execution control of the AS-i master. The
flags are updated by the AS-i master immediately after each change.
The execution control flags are saved in the following register:

Description
Initial value at power-on
COK
Config_OK
1 (TRUE):
The configuration of all AS-i slaves on the
network corresponds to the projection data
(CDI=PCD for all activated slaves) &&
(LDS=LPS=LAS)
Exception:
Flag APF = 1 and LPS = empty, then COK
= 1
0 (FALSE)
S0
LDS.0
1 (TRUE):
Slave with address 0 found
0 (FALSE)
AN
Auto_Address_Assign
1 (TRUE):
Auto addressing possible
(protected mode = active && auto
addressing = active && PCD = CDI &&
LDS <=
LPS)
0 (FALSE)
AA
Auto_Address_Available
1 (TRUE):
All the necessary conditions for auto
addressing are fulfilled. The master waits
for slave 0.
0 (FALSE)
CA
Configuration_Active
0 (FALSE):
1 (TRUE):
Master in protected mode
Master in projection mode
0 (FALSE)
NOA
Normal_Operation_Active
1 (TRUE):
Master is in the normal mode
(The AS-i master has communicated with
at least one slave since the last offline
phase. Even if the slave disappears after
this, the signal will remain set.)
0 (FALSE)
APF
Asi_Power_Fail
0 (FALSE):
1 (TRUE):
AS-i voltage OK
AS-i voltage too low
1 (TRUE)
OR
Offline_Ready
1 (TRUE):
Master has gone through the offline phase
and waits for:
APF = 0 and a timeout of 1s
0 (FALSE)
POK
Periphery_OK
1 (TRUE):
No peripheral faults present, all bits of
LPF = 0.
0 (FALSE)
AAE
Auto_Address_Enable
1 (TRUE):
Auto addressing switched on
(Echo of Set_Auto_Address_Enable of
host)
0 (FALSE)
DEA
Data_Exchange_Active
1 (TRUE):
Data exchange between master and
slaves activated (reflects DEA of host
flags)
1 (TRUE)
0 (FALSE):
Instead of the data exchange, ReadID is
continually executed on the slaves.
PE
Protocol Error
1 (TRUE):
0 (FALSE):
CTT protocol error
No CTT protocol error
0 (FALSE)
