Atmel ATF15xx Family: ISP Devices User Guide
This section describes important guidelines and information about ISP that all users
must pay attention to when performing ISP operations on Atmel ISP devices.
1. Make sure all ISP devices on your circuit board are erased before programming.
2. Make sure the red LED on the back of the Atmel-ISP cable is on when
3. Verify that the correct ISP cable is used.
4. If a parallel cable is used to connect the ISP cable to the PC’s parallel port, make

board is powered up and the LED on the back of the ISP cable is turned on, then
connect the other side of the ISP cable to the PC’s parallel port.

To prevent the use of the JTAG port pins by any of the ISP devices.
This will enable the JTAG port.
All Atmel ATF15xx devices are shipped in the erased state so that they are ISP-
ready.
To ensure that the ISP cable is connected properly.
Atmel-ISP software defaults to using the Atmel-ISP cable.
Must change cable type if using ByteBlaster/ByteBlasterMV cable.
Parallel cable longer than 6 feet might introduce communication problems
between the ISP cable and the parallel port.
To eliminate possible communication problem.
Self-Calibrate and Manual Calibration allow the user to reduce the transfer
speed of the JTAG signals from the PC’s parallel port to the JTAG device chain.
The ISP software may have problems running on PCs with Auto mode configu-
ration for parallel port.
Change your BIOS port settings to either ECP or EPP mode.
Confirm your port address setting before using the software.
Default settings are: 0378H for LPT1; 0278H for LPT2.
Other port addresses must be entered manually.
