Function
Transmit Frame Sync (Serial Ports 0, 1).
Receive Frame Sync (Serial Ports 0, 1).
EPROM Boot Select. When EBOOT is high, the ADSP-21061 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. Must be tied to GND.
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-21061 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-21061. The instruction cycle rate is equal to CLKIN. CLKIN may
not be halted, changed, or operated below the minimum specified frequency.
Processor Reset. Resets the ADSP-21061 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 kΩ internal pull-up resistor.
Test Data Input (JTAG). Provides serial data for the boundary scan logic. TDI has a 20 kΩ 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-21061. TRST has a 20 kΩ internal pull-up resistor.
Emulation Status. Must be connected to the ADSP-21061 EZ-ICE target board connector only. EMU has a
50 kΩ internal pull-up resistor.
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.
