JTAG Interface Bus
The joint test action group (JTAG) IEEE 1149.1 stan-
dard defines a unique method for in-circuit testing and
programming. The MAXQ7665A–MAXQ7665D conform
to this standard, implementing an external test access
port (TAP) and internal TAP controller for communica-
tion with a JTAG bus master, such as an automatic test
equipment (ATE) system. For detailed information on
the TAP and TAP controller, refer to
IEEE Standard
1149.1 on the IEEE website at http://standards.ieee.org.
The JTAG on the MAXQ7665A–MAXQ7665D is used for
in-circuit emulation and debug support, but does not
support boundary scan test capability.
The TAP controller communicates synchronously with
the host system (bus master) through four digital I/O
pins: test mode select (TMS), test clock (TCK), test
data input (TDI), and test data output (TDO). The inter-
nal TAP module consists of several shift registers and a
