Meaning:
In[23:0] : Data from Color Space Stage
Out[23:0] : Data to Output FIFO
Out[23:0] = In[23:0]
Out[23:0] = In[7:0, 23:8]
Out[23:0] = In[15:0, 23:16]
Out[23:0] = In[15:8, 23:16, 7:0]
Out[23:0] = In[7:0, 15:8, 23:16]
Out[23:0] = In[23:16, 7:0, 15:8]

The control register modes are
– w: write/read register
– d: register is double latched
– A: register is available only in VPX 3220 A; VPX 3216 B returns valid ACK, although no internal action is performed
– r:
read-only register
The mnemonics used in the Intermetall VPX demo software are given in the last column.
