TYPICAL CONNECTIONS
Figure 6 shows a typical connection scheme.
Many connection possibilities exist since many
DSM pins are multipurpose. This scheme illus-
trates the use of a combined function
BSM
signal
(functions as
BMS
and
MSx
), and many I/O pins. It
also illustrates how to chain the DSM and DSP de-
vices together on the JTAG bus. The JTAG con-
nector definition depends on development and
production environment requirements. A specially
defined connector can be devised to combine the
signals of the FlashLINK and the Analog Devices
emulator. Alternatively, two separate JTAG con-
nectors can be used, one matching the pinout of
FlashLINK and the other matching the emulator pi-
nout.
Keep in mind that signals
BMS
,
IOMS
,
MSx
,
ADDR16, ADDR17, ADDR18 can be connected to
any DSM pin that is a PLD input. I/O pins on Port
B and Port C are more capable (more PLD func-
tions) than Port D pins. It is recommended to use
Port D pins primarily for decode inputs first, leav-
ing pins on Port B and Port C available for general
logic. Figure 6 illustrates a common way to make
connections.
Following are connection options to consider:
Port C JTAG:
Figure 6 shows four JTAG signals
(TMS, TCK, TDI, TDO) connected to the DSM. Al-
ternatively, using six-pin JTAG (two more signals,
TSTAT and
TERR
) can reduce ISP time by as
much as 30% compared to four-pin JTAG. Other
JTAG options include multiplexing JTAG pins with
general I/O (see “Programming In-Circuit using
JTAG ISP” on page 40 and Application Note
AN1153
), or not using JTAG at all. If no JTAG is
used, the DSM device has to be programmed on a
conventional programmer before it is installed on
the circuit board. Using no JTAG makes more
DSM I/O available.
Pins PC2 and PD2.
If not all 288K address loca-
tions need to be decoded in the DSM, then
ADDR18 on pin PD2 is not needed. In this case,
the
IOMS
signal can be connected to pin PD2, free-
ing pin PC2 for general I/O usage.
