20-pin TAP Connector

To build-in support for in-circuit programming of flash or microprocessor devices, Corelis

recommends including supplemental control signals in the TAP interface. The ScanExpress
Programmer can use a 16-pin TAP, similar to Figure A-5, to improve programming time. This

interface adds Write_Strobe*, Ready/Busy*, and ground signals to the standard 5-signal interface.
Terminating resistors (see Table) can improve signal quality.

Boundary-scan Flash Programming 20-Pin TAP Connector (top view)

Corelis’ Fl

ash Programming software supports the external signals Write_Strobe* and Ready/Busy*,

in addition to the standard but slower scanned out/in signals approach.
The  Write_Strobe*  signal  is  active  low  and  should  be  pulled  up  with  a  1K  resistor  on  the  target
board.  It needs to be logically ORed with the flash Write-Enable (WE*) signal so that either the

flash Write-Enable (WE*) signal or the external Write_Strobe* going low will assert the flash WE*
input.
The active low Ready/Busy* signal is typically an open-collector/open-drain signal that ties directly
to the same signal(s) on the Flash device(s). This enables multiple devices to drive it toward the
PXIE-1149.1/4E.
