RealView Logic Tile

Figure F-3 HDRX, HDRY, and HDRZ (upper) pin numbering

F.3.1 JTAG

The JTAG signals for the FPGA on the RealView Logic Tile are routed through the headers to the tile at the top of the stack and from there back down through the tile. There is not a JTAG connector on the RealView Logic Tile. Use the JTAG or USB debug connector on the PB926EJ-S.

If multiple RealView Logic Tiles are stacked on a PB926EJ-S, the JTAG equipment is always connected to the PB926EJ-S and the signals are routed upwards to the top tile and then back down to the PB926EJ-S.

Use the JTAG interface to program the configuration flash in the RealView Logic Tile or to directly load the RealView Logic Tile FPGA image. For more information on JTAG signals, see JTAG and USB debug port support on page 3-96.

F.3.2 Variable I/O levels

All HDRX, HDRY, and HDRZ connector signals on the PB926EJ-S are fixed at 3.3V I/O signalling level.
