4.3.2
Boundary Scan Register Bits and Bit
Order
The boundary scan register contains a cell for each
pin as well as cells for control of bidirectional and
three-state pins. There are “Reserved” bits which
correspond to no-connect (N/C) signals of the
embedded IntelDX2 processor. Control registers
WRCTL, ABUSCTL, BUSCTL, and MISCCTL are
used to select the direction of bidirectional or three-
state output signal pins. A “1” in these cells
designates that the associated bus or bits are floated
if the pins are three-state, or selected as input if they
are bidirectional.
WRCTL controls D31-D0 and DP3–DP0
ABUSCTL controls A31-A2
BUSCTL controls ADS#, BLAST#, PLOCK#,
LOCK#, W/R#, BE0#, BE1#, BE2#, BE3#, M/IO#,
D/C#, PWT, and PCD
MISCCTL controls PCHK#, HLDA, and BREQ
The following is the bit order of the embedded
IntelDX2 processor boundary scan register:
