ATF1502BE
1.3
Flip-flop
The ATF1502BE’s flip-flop has very flexible data and control functions. The data input can come
from either the XOR gate, from a separate product term or directly from the I/O pin. Selecting the
separate product term allows creation of a buried registered feedback within a combinatorial out-
put macrocell. (This feature is automatically implemented by the fitter software). In addition to D,
T, JK and SR operation, the flip-flop can also be configured as a flow-through latch. In this
mode, data passes through when the clock is high and is latched when the clock is low.
The clock itself can be any one of the Global CLK signals (GCK[0 : 2]) or an individual product
term. The flip-flop changes state on the clock’s rising edge. When the GCK signal is used as the
clock, one of the macrocell product terms can be selected as a clock enable. When the clock
enable function is active and the enable signal (product term) is low, all clock edges are ignored.
The flip-flop’s asynchronous reset signal (AR) can be either the Global Clear (GCLEAR), a prod-
uct term, or always off. AR can also be a logic OR of GCLEAR with a product term. The
asynchronous preset (AP) can be a product term or always off.
1.4
Extra Feedback
The ATF1502BE macrocell output can be selected as registered or combinatorial. The extra bur-
ied feedback signal can be either combinatorial or a registered signal regardless of whether the
output is combinatorial or registered. (This enhancement function is automatically implemented
by the fitter software.) Feedback of a buried combinatorial output allows the creation of a second
latch within a macrocell.
1.5
I/O Control
The output enable multiplexer (MOE) controls the output enable signal. Each I/O can be individ-
ually configured as an input, output or bi-directional pin. The output enable for each macrocell
can be selected from the true or complement of the two output enable pins, a subset of the I/O
pins, or a subset of the I/O macrocells. This selection is automatically done by the fitter software
when the I/O is configured as an input or bi-directional pin.
1.6
Global Bus/Switch Matrix
The global bus contains all input and I/O pin signals as well as the buried feedback signal from
all 32 macrocells. The switch matrix in each logic block receives as its inputs all signals from the
global bus. Under software control, up to 40 of these signals can be selected as inputs to the
logic block.
1.7
Foldback Bus
Each macrocell also generates a foldback product term. This signal goes to the regional bus and
is available to all 16 macrocells within the logic block. The foldback is an inverse polarity of one
of the macrocell’s product terms. The 16 foldback terms in each logic block allow generation of
high fan-in sum terms or other complex logic functions with little additional delay.
