Output Macrocell (OMC)
Eight of the OMCs, McellA0-McellA7, are connect-
ed to Port A pins. The other eight Macrocells,
McellB0-McellB7, are connected to Ports B pins.
OMCs may be used for internal feedback (buried
registers), or their outputs may be routed to exter-
nal Port pins.
The OMC architecture is shown in
Figure
9., page 30
. As shown in the figure, there are na-
tive product terms available from the AND Array,
and borrowed product terms available (if unused)
from other OMC. The polarity of the product term
is controlled by the XOR gate. The 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 OMC block can be configured
as a D, T, JK, or SR type in PSDsoft Express
.
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.
