The signals for the peripheral bus can be generated by any of the four
dedicated inputs or signals on the row interconnect channels, as shown in
Figure
peripheral bus correlates to the number of columns in the FLEX 8000
device. EPF8282A and EPF8282AV devices use 13 channels; EPF8452A,
EPF8636A, EPF8820A, and EPF81188A devices use 21 channels; and
EPF81500A devices use 27 channels. The first LE in each LAB is the source
of the row channel signal. The six peripheral control signals (12 in
EPF81500A devices) can be accessed by each IOE.
