This standard describes a series of mandatory and optional programming instructions and associated data registers that define a standard methodology for accessing and configuring programmable devices. These additional registers and instructions extend the capabilities of devices that comply with IEEE Std 1149.1TM - 2001 such that the IEEE Std 1149.1-2001 Test Access Port may be used for configuration activities. A data description format and extensions to Boundary-Scan Description Language (BSDL) are also specified that provide for the development of standardized automation tools for device programming.
In order to increase the general applicability of the standard to a broader array of implementation technologies (specifically flash memory technology), the working group has decided to specify and standardize the description of adaptive configuration algorithms within the context of 1532. These changes will allow flash programmable devices that are 1532 compliant to be more easily developed.
Revision Standard - Inactive-Withdrawn.
The communication protocol described by IEEE Std 1149.1
-2001 (Standard Test Access
Port and Boundary-Scan Architecture) has been adopted by this standard for providing
standardized programming access and methodology for programmable integrated circuit devices.
Devices that implement this standard will first be compliant with IEEE Std 1149.1-2001, which is
used for testing purposes. A device, or set of devices, implementing this standard can be programmed
(written), read back, erased, and verified, singly or concurrently, with a standardized set
of resources. Sample implementation and application details (which are not part of this standard)
are included for illustrative purposes.
