Output Macrocell (OMC)
Eight of the Output Macrocells (OMC) are con-
nected to Ports A and B pins and are named as
McellAB0-McellAB7. The other eight macrocells
are connected to Ports B and C pins and are
named as McellBC0-McellBC7. If an McellAB out-
put is not assigned to a specific pin in PSDabel,
the Macrocell Allocator block assigns it to either
Port A or B. The same is true for a McellBC output
on Port B or C. Table 13 shows the macrocells and
port assignment.
The Output Macrocell (OMC) architecture is
shown in Figure 13. As shown in the figure, there
are native product terms available from the AND
Array, and borrowed product terms available (if
unused) from other Output Macrocells (OMC). The
polarity of the product term is controlled by the
Table 13. Output Macrocell Port and Data Bit Assignments

XOR gate. The Output Macrocell (OMC) can im-
plement either sequential logic, using the flip-flop
element, or combinatorial logic. The multiplexer
selects between the sequential or combinatorial
logic outputs. The multiplexer output can drive a
port pin and has a feedback path to the AND Array
inputs.
The flip-flop in the Output Macrocell (OMC) block
can be configured as a D, T, JK, or SR type in the
PSDabel program. The flip-flop’s clock, preset,
and clear inputs may be driven from a product
term of the AND Array. Alternatively, CLKIN (PD1)
can be used for the clock input to the flip-flop. The
flip-flop is clocked on the rising edge of CLKIN
(PD1). The preset and clear are active High inputs.
Each clear input can use up to two product terms.
