IEEE 1149.1 Test Access Port (JTAG)
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.
