PORT B WORD-WIDTH SELECTION
NOTES:
1.
The heavy black borders on register segments indicate the only
data paths used. The other byte segments of Port B do not par-
ticipate in the data path during defunneling.
2.
The defunneling process does not change the ordering of bits
within a byte. Halfwords (Figure 7a) or bytes (Figure 7b) are
transferred in parallel form from Port B to Port A.
3.
The word-width setting may be changed during system operation;
however, two clock intervals should be allowed for these signals
to settle, before again attempting to send data, and three
dummy words should be passed through initially. Also, incom-
plete data words may occur, when the word width is changed
from shorter to longer at an inappropriate point in the data block
passing through the FIFO.
