Bit No.
Type
= 0: More than 60 zeros are detected in a 40ms fixed window and this status persists for Mx40ms. Here ‘M’ is decided by the AISCTH[7:0] bits
= 1: Less than 61 zeros are detected in a 40ms fixed window and this status persists for Nx40ms. Here ‘N’ is decided by the AISDTH[7:0] bits
The Yellow Alarm is detected when the frame is synchronized.
