Automatic Synchronization Configuration

5.7.1
In addition to configuring the analog input muxes, ain_sel[2:0]controls automatically the associated synchronization channel routing.
Refer to Figure 9 and the ain_sel[2:0]

Manual Synchronization Configuration

5.7.2
Figure 10 shows the input synchronization muxes, which can be controlled manually as well as automatically. Manual control is enabled
via emb_sync_sel_man_en; and
sync processor. This section describes the control bits for manual operation.
emb_sync_sel_man_en, AFE, Address 0x02[6]
This control is used to enable manual selection of embedded synchronization inputs to synchronization strippers. In automatic mode,
ain_sel[3:0] makes the selection. In manual mode, emb_sync_1_selman[1:0] and emb_sync_2_selman[1:0] makes the selection.
