Introduction

Figure 1-1. Single-device JTAG Configuration
Note:
You will need to reserve space on your circuit board to accommodate a 10-pin
male header for the JTAG interface. The pinout for this header must match the
Atmel-ISP cable connector pinout. The JTAG interface pins for each Atmel
device must also be connected to this header.

Multiple-device
Programming
Atmel ISP devices can be configured as part of a JTAG daisy chain. Once the daisy
chain is configured, multiple Atmel ISP devices can be programmed at the same time
(Parallel ISP). Figure 1-2 shows the configuration for multiple-device programming.
Figure 1-2. Multiple-device JTAG Chain Configuration
TDI, TMS, TCK and TDO comprise the JTAG interface. The ISP software allows you to
create a JTAG daisy chain for multiple devices, including non-Atmel devices, and imple-
ment parallel ISP for Atmel devices.
To create a JTAG daisy chain to implement parallel ISP, perform the following steps:
1.
Connect the TMS and TCK pin for each device in the JTAG chain to the appro-
priate pins on the 10-pin header on your circuit board.
2.
Connect the TDI pin from the first device to the TDI pin on the 10-pin header.
3.
Connect the TDO pin from first device to the TDI pin of the next device. Continue
this process until all except the last one are connected.
4.
Connect the TDO pin from the last device to the TDO pin on the 10-pin header.
