I'm getting an issue on TD LAN :

Config 1 :
-Transmitter :
ATS400=0xA10000
ATS401=0xFFFFFF

-Receiver :
ATS400=0xA00000
ATS401=0xF00000

Sending frame from Transmitter to receiver :
Receiver : AT$RL=1,30
Transmitter : AT$SL=DEADBEEF
Transmission OK

Config2:
-Transmitter: unchanged

-Receiver:
ATS400-0xA00001, mask unchanged

Sending frame from Transmitter to receiver :
Receiver : AT$RL=1,30
Transmitter : AT$SL=DEADBEEF
Transmission ERROR

Both Receiver & Transmitted are using SOFT1445

from my understanding, config2 should work as well, no ?

Thanks in advance for help
