1.0 J Drive - What is IEEE-STD-1532?


What is IEEE-STD-1532?


IEEE-STD-1532 is a new IEEE standard for communicating with devices in a JTAG chain. IEEE 1532 is a "superset" of the previous standard, IEEE 1149.1; this means that 1532-compliant devices can coexist with 1149.1-compliant devices in the same boundary scan chain.

Software support for IEEE-STD-1532 is provided by J Drive.

Software support for IEEE-STD-1149.1 is provided by JTAG Programmer.
