	DSP~LINK3 Interface

5.3.Interface Signals

The DSP~LINK3 interface consists of two 16-bit bi-directional buffers for data, a 16-bit address latch, and a control signal buffer. The control signals are terminated via a SCSI terminator. The DSP~LINK3 interface signals are:

∙32 data I/O lines: D[31..0]

∙16 address outputs: A[15..0] A15 and A14 are used for slave device (board) selection.

∙/DSTRB, /ASTRB, R/W and /RST outputs

∙Tri-state ready (/RDY) input

∙4 open-collector interrupt inputs (IRQ0 to IRQ3). These interrupt are logically OR’ed and routed to the INT7 line of node A’s ‘C6x.

Refer to DSP~LINK3 specification for details (available from Spectrum’s internet web site at http://www.spectrumsignal.com)

5.4.DSP~LINK3 Reset

Bit D0 of the DSP~LINK3 register controls the DSP~LINK3 reset line. This register is located at address 016D 8018h of node A. Setting bit D0 to “1” asserts the DSP~LINK3 reset line; setting it to “0” releases the reset. DSP~LINK3 resets must be at least 1 µs long. This reset is entirely under software control.

The DSP~LINK3 reset line will also be asserted during /SYSRESET or secondary control register board reset conditions.
