Function
Boot Memory Select. Output: Used as chip select for boot EPROM devices (when EBOOTBCD = 1,
LBOOTBCD = 0). In a multiprocessor system, BMS is output by the bus master. Input: When low,
indicates that no booting will occur and that SHARC_B, C, D will begin executing instructions from
external memory. See table below. This input is a system configuration selection which should be
hardwired.

Timer Expired. (Individual TIMEXP from y = SHARC_A, SHARC_B, SHARC_C, SHARC_D) Asserted
for four cycles when the timer is enabled and TCOUNT decrements to zero.
Clock In. (Common to all SHARCs) External clock input to the AD14160/AD14160L. The instruction
cycle rate is equal to CLKIN. CLKIN may not be halted, changed, or operated below the minimum specified
frequency.
Module Reset. (Common to all SHARCs) Resets the AD14160/AD14160L to a known state. This input
must be asserted (low) at power-up.
Test Clock (JTAG). (Common to all SHARCs) Provides an asynchronous clock for JTAG boundary
scan.
Test Mode Select (JTAG). (Common to all SHARCs) 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 chain starting at SHARC_A.
TDI has a 20 k internal pull-up resistor.
Test Data Output (JTAG). Serial scan output of the boundary scan chain path, from SHARC_D.
Test Reset (JTAG). (Common to all SHARCs) Resets the test state machine. TRST must be asserted
(pulsed low) after power-up or held low for proper operation of the AD14160/AD14160L. TRST has a
20 k internal pull-up resistor.
Emulation Status. (Common to all SHARCs) Must be connected to the ADSP-2106x EZ-ICE target
board connector only.
Power Supply. Nominally +5.0 V dc for 5 V devices or +3.3 V dc for 3.3 V devices (50 pins).
Power Supply Return. (64 pins).
