Internal Register Data Access
The figures in this section detail typical internal register data read and write cycles in indexed address mode for 16 and
8-bit modes. This includes an index register write followed by either a data read or write.
16-BIT READ
One of the Index Registers is set as described above. The address is then set to access the lower WORD of the corre-
sponding Data Register and FIFOSEL is held low. Read data is driven on D[15:0] during RD active. The cycle repeats
for the upper WORD of the Data Register.
