IEEE 1149.1 Test Access Port (JTAG)
31.1 Introduction
The Joint Test Action Group, or JTAG, is a dedicated user-accessible test logic, that complies with
the IEEE 1149.1 standard for boundary-scan testability, to help with system diagnostic and
manufacturing testing.
This architecture provides access to all data and chip control pins from the board-edge connector
through the standard four-pin test access port (TAP) and the JTAG reset pin, TRST.
