PDICO is an AVR specific instruction and using the JTAG TAP as an alternative interface
towards the PDI (Programming and Debug Interface).
The active states are:
The supported data registers that can be connected between TDI and TDO are:
The Bypass Register consists of a single Shift Register stage. When the Bypass Register is
selected as path between TDI and TDO, the register is reset to 0 when leaving the Capture-DR
controller state. The Bypass Register can be used to shorten the scan chain on a system when
the other devices are to be tested.
D
• Capture-DR: Loads a logical "0" into the Bypass Register.
• Shift-DR: The Bypass Register cell between TDI and TDO is shifted.
• Capture-DR: Parallel data from the PDI is sampled into the PDICOM data register.
• Shift-DR: The PDICOM data register is shifted by the TCK input.
• Update-DR: Commands or operands are parallel-latched from the PDICOM data register into
• Bypass register (Ref: register A in
• Device Identification register (Ref: registers C in
• Boundary-scan chain (Ref: register D in
• PDICOM data register (Ref: register B in
