Function
Transmit Frame Sync (Serial Ports 0, 1).
Receive Frame Sync (Serial Ports 0, 1).
Link Port Data (Link Ports 0–5). Each LxDAT pin has a 50 k: internal pull-down resistor that is enabled or
disabled by the LPDRD bit of the LCOM register.
Link Port Clock (Link Ports 0–5). Each LxCLK pin has a 50 k: internal pull-down resistor that is enabled or
disabled by the LPDRD bit of the LCOM register.
Link Port Acknowledge (Link Ports 0–5). Each LxACK pin has a 50 k: internal pull-down resistor that is
enabled or disabled by the LPDRD bit of the LCOM register.
EPROM Boot Select. When EBOOT is high, the ADSP-2106x is configured for booting from an 8-bit EPROM.
When EBOOT is low, the LBOOT and BMS inputs determine booting mode. See the table in the BMS pin
description below. This signal is a system configuration selection that should be hardwired.
Link Boot. When LBOOT is high, the ADSP-2106x is configured for link port booting. When LBOOT is low,
the ADSP-2106x is configured for host processor booting or no booting. See the table in the BMS pin
description below. This signal is a system configuration selection that should be hardwired.
Boot Memory Select. Output: Used as chip select for boot EPROM devices (when EBOOT = 1, LBOOT = 0).
In a multiprocessor system, BMS is output by the bus master. Input: When low, indicates that no booting will
occur and that ADSP-2106x will begin executing instructions from external memory. See table below. This
input is a system configuration selection that should be hardwired. *Three-statable only in EPROM boot
mode (when BMS is an output).

Clock In. External clock input to the ADSP-2106x. The instruction cycle rate is equal to CLKIN. CLKIN should
not be halted, changed, or operated below the minimum specified frequency.
Processor Reset. Resets the ADSP-2106x to a known state and begins program execution at the program
memory location specified by the hardware reset vector address. This input must be asserted (low) at
power-up.
Test Clock (JTAG). Provides an asynchronous clock for JTAG boundary scan.
Test Mode Select (JTAG). Used to control the test state machine. TMS has a 20 k: internal pull-up resistor.
Test Data Input (JTAG). Provides serial data for the boundary scan logic. TDI has a 20 k: internal pull-up
resistor.
Test Data Output (JTAG). Serial scan output of the boundary scan path.
Test Reset (JTAG). Resets the test state machine. TRST must be asserted (pulsed low) after power-up or held
low for proper operation of the ADSP-2106x. TRST has a 20 k: internal pull-up resistor.
Emulation Status. Must be connected to the ADSP-2106x EZ-ICE target board connector only.
Reserved, leave unconnected.
Power Supply; nominally 5.0 V dc for 5 V devices or 3.3 V dc for 3.3 V devices. (30 pins).
Power Supply Return. (30 pins).
Do Not Connect. Reserved pins which must be left open and unconnected.
