Private JTAG Instructions
NEXUS_ACCESS
BYPASS
Table 27-14. CLAMP Details
This instruction selects the 1-bit Bypass Register as Data Register.
Starting in Run-Test/Idle, the CLAMP instruction is accessed the following way:
Table 27-15. BYPASS Details
The 32-bit AVR defines a number of private JTAG instructions, not defined by the JTAG stan-
dard. Each instruction is briefly described in text, with details following in table form.
This instruction allows Nexus-compliant access to the On-Chip Debug registers through the
SAB. The 7-bit register index, a read/write control bit, and the 32-bit data is accessed through
the JTAG port.
The data register is alternately interpreted by the SAB as an address register and a data regis-
ter. The SAB starts in address mode after the NEXUS_ACCESS instruction is selected, and
toggles between address and data mode each time a data scan completes with the busy bit
cleared.
NOTE : The polarity of the direction bit is inverse of the Nexus standard.

9. Return to Run-Test/Idle.
1. Select the IR Scan path.
2. In Capture-IR: The IR output value is latched into the shift register.
3. In Shift-IR: The instruction register is shifted by the TCK input.
4. Return to Run-Test/Idle.
5. Select the DR Scan path.
6. In Capture-DR: A logic ‘0’ is loaded into the Bypass Register.
7. In Shift-DR: Data is scanned from TDI to TDO through the Bypass register.
8. Return to Run-Test/Idle.
