TCC76x
Specification Rev. 0.07
32-bit RISC Microprocessor for Digital Media Player
February 23, 2005
JTAG DEBUG INTERFACE
21 JTAG DEBUG INTERFACE
The TCC76x has the ARM940T core as main controller, and JTAG interface for
developing the application programs. It can be connected with OPENice32 of AIJI
System or Multi-ICE of ARM or other third party’s in-circuit emulator supporting for
ARM940T core.
With the use of in-circuit emulator, users can easily develop the program for their own
system. It provides hardware breakpoints, internal register monitoring, memory dump, etc.
Refer to user’s manual of in-circuit emulator for more detail functions of it.
Figure 21.1 shows the application circuit for JTAG interface. Care must be taken not to
combine system reset with JTAG reset signal.
