Table 13. Output Micro
Cell Port and Data Bit Assignments
The Output Micro
Cell (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 OMCs. The polarity of the product term is controlled by the
XOR gate. The OMC can implement 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 OMC can be configured as a D, T, JK, or SR type in the PSDsoft
program. The flip-flop
’
s clock, preset, and clear inputs may be driven from a product term
of the AND array. Alternatively, the external CLKIN signal can be used for the clock input
to the flip-flop. The flip-flop is clocked on the rising edge of the clock input. The preset and
clear are active-high inputs. Each clear input can use up to two product terms.
