Figure 19-16 16-bit Upstream Reception
Data Reception without Address Field
Frame reception for a 12-bit data frame is selected by USR.UFT = 0. The reception
scheme is comparable with that of the 16-bit data frame reception but there are a few
differences:
•
The upstream counter is initially loaded with 01100
•
The received frame content is always stored in register UD0.
•
Bit field UD0.LABF is always loaded with 00
