2.12 Joint Test Access Group
The Bt8370/8375/8376 incorporates printed circuit board testability circuits in
compliance with IEEE Std. P1149.1a–1993, IEEE Standard Test Access Port and
Boundary–Scan Architecture, commonly known as JTAG (Joint Test Action
Group).
TAP provides a standard interface through which instructions and test data are
communicated (see
(BSDL) file for the Bt8370/8375/8376 is available from the factory upon request.
internal power on reset circuit resets the JTAG port.
