Note 1:
This coding of the TDSA, TDSB, E3M, and STS bits allows AIS generation to be enabled by
holding TDSA = 0 and changing TDSB from 0 to 1. The type of DS3 AIS signal is selected by the
STS bit with E3M = 0.
If E3M and/or STS are changed when {TDSA,TDSB} 00, TDSA and TDSB must both be cleared
to 0. After they are cleared, TDSA and TDSB can be configured to transmit a pattern in the new
operating mode.
