NEXUS_ACCESS
bold text. I.e. given the pattern " aaaaaaar xxxxxxxx xxxxxxxx xxxxxxxx xx", the shift register is
34 bits, but the test or debug unit may choose to shift only 8 bits " aaaaaaar ".
The following describes how to interpret the fields in the instruction description tables:
Table 36-4.
This instruction allows Nexus-compliant access to on-chip debug registers through the SAB.
OCD registers are addressed by their register index, as listed in the AVR32 Technical Reference
Manual. The 7-bit register index and 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.
Starting in Run-Test/Idle, OCD registers are accessed in the following way:
Instruction
IR input value
IR output value
DR Size
DR input value
DR output value
1. Select the DR Scan path.
2. Scan in the 7-bit address for the OCD register and a direction bit (1=read, 0=write).
3. Go to Update-DR and re-enter Select-DR Scan.
4. For a read operation, scan out the contents of the addressed register. For a write oper-
5. Return to Run-Test/Idle.
ation, scan in the new contents of the register.
Instruction description
Description
Shows the bit pattern to shift into IR in the Shift-IR state in order to select this
instruction. The pattern is show both in binary and in hexadecimal form for
convenience.
Example: 10000 (0x10)
Shows the bit pattern shifted out of IR in the Shift-IR state when this instruction is
active.
Example: peb01
Shows the number of bits in the data register chain when this instruction is active.
Example: 34 bits
Shows which bit pattern to shift into the data register in the Shift-DR state when this
instruction is active. Multiple such lines may exist, e.g. to distinguish between reads
and writes.
Example: aaaaaaar xxxxxxxx xxxxxxxx xxxxxxxx xx
Shows the bit pattern shifted out of the data register in the Shift-DR state when this
instruction is active. Multiple such lines may exist, e.g. to distinguish between reads
and writes.
Example: xx xxxxxxxx xxxxxxxx xxxxxxxx xxxxxxeb
