Description
ORA
Output Ready
O
ORA is synchronized to the LOW-to-HIGH transition of CLKA. When ORA is LOW, FIFO2 is
Flag
(Port A)
empty and reads from its memory are disabled. Ready data is present on the output register
of FIFO2 when ORA is HIGH. ORA is forced LOW when FlFO2 is reset and goes HIGH on the
third LOW-to-HIGH transition of CLKA after a word is loaded to empty memory.
ORB
Output Ready
O
ORB is synchronized to the LOW-to-HIGH transition of CLKB. When ORB is LOW, FlFO1 is
Flag
(Port B)
empty and reads from its memory are disabled. Ready data is present on the output register of FIFO1
when ORB is HIGH. ORB is forced LOW when FIFO1 is reset and goes HIGH on the third LOW-to-
HIGH transition of CLKB after a word is loaded to empty memory.
RST1
FIFO1 Reset
I
To reset FIFO1, four LOW-to-HIGH transitions of CLKA and four LOW-to-HIGH transitions of CLKB
must occur while
RST1 is LOW. The LOW-to-HIGH transition of RST1 latches the status of FS0
and FS1 for
AFA and AEB offset selection. FIFO1 must be reset upon power up before data is
written to its RAM.
RST2
FIFO2 Reset
I
To reset FIFO2, four LOW-to-HIGH transitions of CLKA and four LOW-to-HIGH transitions of CLKB
must occur while
RST2 is LOW. The LOW-to-HIGH transition of RST2 latches the status of FS0
and FS1 for
AFB and AEA offset selection. FIFO2 must be reset upon power up before data is
written to its RAM.
W/
RA
Port A Write/
I
A HIGH selects a write operation and a LOW selects a read operation on port A for a LOW-to-HIGH
Read Select
transition of CLKA. The A0-A35 outputs are in the HIGH impedance state when W/
RA is HIGH.
W/RB
Port B Write/
I
A LOW selects a write operation and a HIGH selects a read operation on port B for a LOW-to-HIGH
Read Select
transition of CLKB. The B0-B35 outputs are in the high-impedance state when
W/RB is LOW.
