8077H–AVR–12/09
IDCODE; 0x3
SAMPLE/PRELOAD; 0x2
BYPASS; 0xf
CLAMP; 0x4
HIGHZ; 0x5
The active states are:
IDEOCE is mandatory and the instruction for selecting the 32 bit ID-Register as Data Register.
The ID-Register consists of a version number, a device number and the manufacturer code cho-
sen by JEDEC. This is the default instruction after power-up.
The active states are:
SAMPLE/RELOAD mandatory and the instruction for pre-loading the output latches and taking a
snapshot of the input/output pins without affecting system operation. However, the output
latches are not connected to the pins. The Boundary-scan Chain is selected as Data Register.
Note that since each of the SAMPLE and PRELOAD instructions implements the functionality of
the other, they share a common binary value, and can be treated as one single merged
instruction.
The active states are:
BYPASS is mandatory and the instruction for selecting the Bypass Register for Data Register.
The active states are:
CLAMP is optional and the instruction for allowing the state of the input/output pins to be deter-
mined from the preloaded output latches. The Bypass register is selected as Data Register.
The active states are:
HIGHZ is optional and the instruction for putting all outputs in an inactive drive state (e.g. high
impedance). The Bypass register is selected as Data Register.
The active states are:
• Capture-DR: Data on the external pins are sampled into the Boundary-scan Chain.
• Shift-DR: Data in the Boundary-scan Chain is shifted by the TCK input.
• Update-DR: Data from the scan chain is applied to output pins.
• Capture-DR: Data in the IDCODE Register is sampled into the Device Identification register.
• Shift-DR: The IDCODE scan chain is shifted by the TCK input.
• Capture-DR: Data on the external pins are sampled into the Boundary-scan Chain.
• Shift-DR: The Boundary-scan Chain is shifted by the TCK input.
• Update-DR: Data from the Boundary-scan chain is applied to the output latches. However,
• Capture-DR: Loads a logic "0" into the Bypass Register.
• Shift-DR: The Bypass Register cell between TDI and TDO is shifted.
• Capture-DR: Loads a logical "0" into the Bypass Register.
• Shift-DR: The Bypass Register cell between TDI and TDO is shifted.
the output latches are not connected to the pins.
