Meaning of the Bits in Bytes 0 to 33
S Bit = 0 :
LAS (bytes 2 to 9): The AS-i slave is not activated
LDS (bytes 10 to 17): The AS-i slave was not detected
LPS (bytes 18 to 25): The AS-i slave is not configured
LPF (bytes 26 to 33): The AS-i slave is not signaling a peripheral fault
S Bit = 1:
LAS (bytes 2 to 9): The AS-i slave is activated
LDS (bytes 10 to 17): The AS-i slave was detected
LPS (bytes 18 to 25): The AS-i slave is configured
LPF (bytes 26 to 33): The AS-i slave is signaling a peripheral fault

Meaning of the Flags
Flag Meaning
CONFIG_OK This flag is set when the desired (configured) and actual configuration
match.
LDS_0 This flag is set when an AS-i slave exists with address 0.
AUTO_ADDR_ASSIGN This flag is set when the automatic address programming is possible (in
other words, SET_AUTO_ADDR_ENABLE = 1 and there is no
“incorrect” slave connected to the AS-i Interface).
AUTO_ADDR_AVAIL This flag is set when the automatic address programming can be
executed (in other words, exactly one AS-i slave is currently out of
operation).
CONFIG_MODE The flag is set in the configuration mode and reset in the protected mode.
NORMAL_MODE This flag is set when the IE/AS-i LINK is in the normal mode.
(The flag is set when the link is in normal mode)
APF This flag is set when the voltage on the AS-i cable is too low.
OFFLINE_READY The flag is set when the offline phase is active.
PERIPHERY_OK This flag is set when at no AS-i slave is signaling a peripheral fault.
DATA_EXCHANGE_ACTIVE The “DATA_EXCHANGE_ACTIVE” flag is set when data is being
exchanged in normal mode.
