4)64-group serial data mode 

Support 64 sets of serial data, defined as follows:

blob.png 

Under serial mode, there are 64 data cables totally. Each cable can drive one LED bar independently. 

In case of horizontal LED bar, the default is, Data1 drives the first row from the top, and Data64 drives the 64th row. 

In case of vertical LED bar, the default is, Data1 drives the first column of from the left, and Data64 drives the 64th column.
