Built-In Self-Test Operation (BIST)
No self-test functions are supported by the ADSP-2126x.
EMUIDLE Instruction
The
instruction places the DSP in the idle state and triggers an
EMUIDLE
emulator interrupt. This operation uses the
ware breakpoint. When the
clock counter immediately halts.
Private Instructions
Table 6-2
lists the private instructions that are reserved for emulation and
memory test. The ADSP-2126x JTAG ICE emulator uses the TAP and
boundary scan as a way to access the processor in the target system. The
JTAG ICE emulator requires a target board connector for access to the
TAP.
