The JTAG circuitry and ISP instruction set in MAX II devices is compliant to the IEEE
1532-2002 programming specification. This provides industry-standard hardware and
software for in-system programming among multiple vendor programmable logic
devices (PLDs) in a JTAG chain.
The MAX II 1532 BSDL files will be released on the Altera website when available.
The Jam STAPL JEDEC standard, JESD71, can be used to program MAX II devices
with in-circuit testers, PCs, or embedded processors. The Jam byte code is also
supported for MAX II devices. These software programming protocols provide a
compact embedded solution for programming MAX II devices.
For more information, refer to the
chapter in the MAX II Device Handbook.
During in-system programming, 1532 instructions, addresses, and data are shifted
into the MAX II device through the TDI input pin. Data is shifted out through the TDO
output pin and compared against the expected data. Programming a pattern into the
device requires the following six ISP steps. A stand-alone verification of a
programmed pattern involves only stages 1, 2, 5, and 6. These steps are automatically
executed by third-party programmers, the Quartus II software, or the Jam STAPL and
Jam Byte-Code Players.
