.
2. Maximum cable loss at 772 KHz.
3. When reading LEN, bit values appear inverted.
B2
revision silicon will fix this so the bits read back
correctly.

Function
7-0
AIS7-AIS0
Respective bit(s) are set to

every time the receiver detects a AIS condition in
transceivers 7-0.
1. On power-up all the register bits are set to
0
. All AIS interrupts are cleared by a single read operation.
