DESCRIPTION
DATABUS
D[35:0]
36-bit Input-Port Databus.
The D port is the input port for the FIFO memory array, the resource
registers, and the mailbox, or it may be directly connected to the output port. See Figure 4.
D[35:0] is synchronous to the rising edge of CKI.
Q[35:0]
Three-State 36-Bit Output-Port Databus.
The Q port is the output port for the FIFO memory array,
the resource registers, and the mailbox, or it may be directly connected to the input port. See Figure
4. Q[35:0] is synchronous to the rising edge of CKO. The lower 16 bits of the Q port (Q[15:0]) may
also be used as the input port for the resource register.
CLOCKS
CKI
Input-Port Clock.
CKI is a free-running waveform controlled by an oscillator. It may be irregular or
asynchronous if minimum clock-HIGH times and clock-LOW times are met.
CKO
Output-Port Clock.
CKO is a free-running waveform controlled by an oscillator. It may be irregular
or asynchronous if minimum clock-HIGH times and clock-LOW times are met.
