MAX 3000A Programmable Logic Device Family Data Sheet
Preliminary Information
IEEE Std.
1149.1 (JTAG)
Boundary-Scan
Support
MAX 3000A devices include the JTAG BST circuitry defined by IEEE Std.
1149.1-1990. Table 4 describes the JTAG instructions supported by
MAX 3000A devices. The pin-out tables starting on page 29 of this data
sheet show the location of the JTAG control pins for each device. If the
JTAG interface is not required, the JTAG pins are available as user I/O
pins.
The instruction register length of MAX 3000A devices is 10 bits. The
the boundary-scan register length and device IDCODE information for
MAX 3000A devices.
Table 4. MAX 3000A JTAG Instructions
JTAG Instruction
Description
SAMPLE/PRELOAD
Allows a snapshot of signals at the device pins to be captured and examined during
normal device operation, and permits an initial data pattern output at the device pins.
EXTEST
Allows the external circuitry and board-level interconnections to be tested by forcing a
test pattern at the output pins and capturing test results at the input pins.
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.
IDCODE
Selects the IDCODE register and places it between the TDI and TDO pins, allowing the
IDCODE to be serially shifted out of TDO.
USERCODE
Selects the 32-bit USERCODE register and places it between the TDI and TDO pins,
allowing the USERCODE value to be shifted out of TDO.
ISP Instructions
These instructions are used when programming MAX 3000A devices via the JTAG ports
with the MasterBlaster, ByteBlasterMV, or BitBlaster cable, or using a Jam File, JBC File,
or SVF File via an embedded processor or test equipment.
