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 MAXQ7666 conforms to this stan-
dard, implementing an external test access port (TAP)
and internal TAP controller for communication 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 MAXQ7666 is used for in-circuit emulation and
debug support, but does not support boundary scan
test capability. Disable the JTAG function after power-
up before normal operation.
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 internal
TAP module consists of several shift registers and a
TAP controller (see Figure 12). The shift registers serve
