Configuration Devices for ACEX, APEX, FLEX & Mercury Devices Data Sheet

Application Note 39 (IEEE 1149.1 (JTAG) Figure9
shows the timing requirements for the JTAG signals.
BYPASS
Places the 1-bit bypass register between the
TDI
and
TDO
pins, which allows the BST
data to pass synchronously through a selected device to adjacent devices during
normal device operation.
Selects the device IDCODE register and places it between
TDI
and
TDO
, allowing the
device IDCODE to be serially shifted out of
TDO
. The device IDCODE for the EPC2 is
shown below:
0000 0001000000000010 00001101110 1
Selects the USERCODE register and places it between
TDI
and
TDO
, allowing the
USERCODE to be serially shifted out of
TDO
. The 32-bit USERCODE is a
programmable user-defined pattern.
These instructions are used when programming an EPC2 device via JTAG ports with
a MasterBlaster, ByteBlaster MV, ByteBlaster, or BitBlaster download cable, or using
a Jam STAPL File (
.jam
), Jam STAPL Byte-Code File (
.jbc
), or SVF File via an
embedded processor.
This function allows the user to initiate the APEX or FLEX configuration process by
tying
nINIT_CONF
to the APEX or FLEX device(s)
nCONFIG
pin(s). After this
instruction is updated, the
nINIT_CONF
pin is driven low. When the Initiate
Configuration instruction is cleared,
nINIT_CONF
is released, which starts the APEX
or FLEX device configuration. This instruction is used by the MAX+PLUS II software,
Jam STAPL Files, and JBC Files.
