Secondary Clock/CE/LSR Mux Connectivity
The Secondary Clock/CE/LSR Mux input sources include:
• Primary Clock input pins
• From routing
The Secondary Clock/CE/LSR Mux outputs feed four clock input switch boxes and eight control input switch boxes
in each PFU. Each slice includes one clock input switch box and two control input switch boxes, one for CE (Clock
Enable) and the other for LSR (Local Set/Reset).
Figure 10-11. Secondary Clock/Control Net (All MachXO)
Primary Clock and Secondary Clock/CE/LSR Distribution Network
The Clock Input Switch Box and Control Input Switch Box are described in Figure 10-12 and Figure 10-13.
Figure 10-14 shows the entire connectivity of the MachXO clock distribution network for each PFU.
