H.2 Multi-drop (8051 9 bit) Mode
Each serial channel of the DUART can be configured to
operate in a wake up mode useful for multi-drop or
multiprocessor applications. This section will first present
the concept of the Multi-Drop Mode. Afterwards, the
function and procedure of operating the DUART in the
Multi-Drop mode is discussed in
Section H.2.1.
H.2.1 Concept of Multi-Drop Mode
This mode is compatible with the serial “Nine bit Mode” of
8051 family microcomputers. In this mode of operation a
“master station”, connected to a maximum of 256 slave
station is possible, as depicted in
Figure 46.
