SDRAM A10 Pin.
Enables applications to refresh an SDRAM in parallel with a host access.
Crystal Oscillator Terminal.
Used in conjunction with CLKIN to enable the ADSP-21065L’s
internal clock generator or to disable it to use an external clock source. See CLKIN.
PWM Output/Event Capture.
In PWMOUT mode, is an output pin and functions as a timer
counter. In WIDTH_CNT mode, is an input pin and functions as a pulse counter/event capture.

CLOCK SIGNALS
The ADSP-21065L can use an external clock or a crystal. See
CLKIN pin description. You can configure the ADSP-21065L
to use its internal clock generator by connecting the necessary
components to CLKIN and XTAL. You can use either a crystal
operating in the fundamental mode or a crystal operating at an
overtone. Figure 4 shows the component connections used for a
crystal operating in fundamental mode, and Figure 5 shows
the component connections used for a crystal operating at an
overtone.

TARGET BOARD CONNECTOR FOR EZ-ICE PROBE
The ADSP-2106x EZ-ICE emulator uses the IEEE 1149.1
JTAG test access port of the ADSP-2106x to monitor and con-
trol the target board processor during emulation. The EZ-ICE
probe requires the ADSP-2106x’s CLKIN, TMS, TCK,
TRST
,
TDI, TDO,
EMU
and GND signals be made accessible on the
target system via a 14-pin connector (a 2 row x 7 pin strip header)
such as that shown in Figure 6. The EZ-ICE probe plugs di-
rectly onto this connector for chip-on-board emulation. You
must add this connector to your target board design if you,
intend to use the ADSP-2106x EZ-ICE.
The total trace length between the EZ-ICE connector and the
furthest device sharing the EZ-ICE JTAG pins should be lim-
ited to 15 inches maximum for guaranteed operation. This
restriction on length must include EZ-ICE JTAG signals, which
are routed to one or more 2106x devices or to a combination of
2106xs and other JTAG devices on the chain.
The 14-pin, 2-row pin strip header is keyed at the Pin 3 loca-
tion—you must remove Pin 3 from the header. The pins must
be 0.025 inch square and at least 0.20 inch in length. Pin spac-
ing should be 0.1
×
0.1 inches. Pin strip headers are available
from vendors such as 3M, McKenzie and Samtec.
