8018P–AVR–08/10
Overview
Features

•
•
•
•
•
The AVR IEEE std. 1149.1 compliant JTAG interface can be used for:
• Testing PCBs by using the JTAG Boundary-scan capability.
• Programming the non-volatile memories, Fuses and Lock bits.
• On-chip debugging.
A brief description is given in the following sections. Detailed descriptions for Programming via
the JTAG interface, and using the Boundary-scan Chain can be found in the sections
ming via the JTAG Interface” on page 316
259, respectively. The On-chip Debug support is considered being private JTAG instructions,
and distributed within ATMEL and to selected third party vendors only.

system. The TAP Controller is a state machine controlled by the TCK and TMS signals. The TAP
Controller selects either the JTAG Instruction Register or one of several Data Registers as the
scan chain (Shift Register) between the TDI – input and TDO – output. The Instruction Register
holds JTAG instructions controlling the behavior of a Data Register.
The ID-Register, Bypass Register, and the Boundary-scan Chain are the Data Registers used
for board-level testing. The JTAG Programming Interface (actually consisting of several physical
and virtual Data Registers) is used for serial programming via the JTAG interface. The Internal
Scan Chain and Break Point Scan Chain are used for On-chip debugging only.
