Auto ISP Mode
Board Configuration
The On-Chip memories and configuration bytes can be programmed using the ISP
mode of the device and Atmel's FLexible In-system Programmer Software (FLIP)
described below.
See Section “FLIP Software”, page 11.
To use ISP mode, no specific configuration is necessary on the board. Only make sure
that the EA pin of the product is tied to Vcc (internal code execution only).
To enter in ISP mode, press both the RESET and ISP buttons simultaneously.
First release the RESET button and then the ISP button. The device enters in
ISP mode.
It allows the host PC application (Atmel Flip software for example) to control the hard-
ware conditions from the serial lines RTS and DTR.
Thus with the Auto ISP mode, the user does not need to push the ISP and RESET
buttons.
To use Auto ISP mode, put the board in the same configuration as ISP mode and also:
Close RTS (J11) jumper
Close DTR (J12) jumper
