5.4.4. Test Data Registers
(Section 12.3.1.b.iv of IEEE 1149.1-1990).
The VPX includes the use of four test data registers.
They are the required bypass and boundary scan regis-
ters, the optional ID code register and the master mode
register.
The bypass register is, as defined, a 1-bit register ac-
cessed by codes 100 through 111, inclusive. Since the
design includes the ID code register, the bypass register
is not placed in the serial path upon power-up or Test-
Logic-Reset.
The master mode is an 8-bit test register which is used
to force the VPX nto special test modes. This is reset
upon power-on-reset. This register supports shift and
update only. It is not recommended to access this regis-
ter. The loading of that register can drive the IC into an
undefined state.
5.4.5. Boundary-Scan Register
(Section 12.3.1.b.v of IEEE 1149.1-1990)
The boundary-scan chain has a length of 38 shift regis-
ters. The scan chain order is specified in the section “Pin
Connections”.
5.4.6. Device Identification Register
(Section 12.3.1.b.vi of IEEE 1149.1-1990)
The manufacturer’s identification code for-INTER-
METALL is “6C”
(hex)
. The general implementation
scheme uses only the 7 LSBs and excludes the MSB,
which is the parity bit. The part number is “4680”
(hex)
.
The version code starts from “1”
(hex)
and changes with
every revision. The version number relates to changes
of the chip interface only.
5.4.7. Performance
(Section 12.3.1.b.vii of IEEE 1149.1-1990)
See section “Specification” for further information.
