Register Write transfer

Register Write transfer can be of two types:
•
Normal Write transfer – channels 0, 1, 2 and 3
•
Streaming Data transfer – channel 2 only
A Register Write transfer can be done through Normal Write transfer - channels 0, 1, 2 and
3 (see <Cross Refs>Section 45.7.3.1, Normal write transfer) as shown in
Figure 552. Register write transfer (showing LFAST frame encapsulation)
