Functional Logic Diagram
Note:
The ATF1500A has 32 bi-directional I/O pins and four dedi-
cated input pins. Each dedicated input pin can also serve
as a global control signal: register clock, register reset or
output enable. Each of these control signals can be
selected for use individually within each macrocell.

Each of the 32 logic macrocells generates a buried feed-
back, which goes to the global bus. Each input and I/O pin
also feeds into the global bus. Because of this global bus-
ing, each of these signals is always available to all 32 mac-
rocells in the device.
