Figure 1. FPSLIC Support Device for Programming FPSLIC Devices
The FPSLIC’s bi-directional CON pin drives the CE input of the FPSLIC Support Device, while the RESET/OE input is
driven by the FPSLIC’s bi-directional INIT pin. This connection works under all normal circumstances, even when the user
aborts the configuration before CON has gone High. A Low level on the RESET/OE input, during FPSLIC reset, clears the
FPSLIC Support Device’s internal address pointer so that the reconfiguration starts at the beginning.
The spare memory can be accessed by in-system programming the ATFS through a two-wire serial interface built in the
FPSLIC device. For more information, refer to the “C Code for Interfacing the FPSLIC AVR Core to AT17 Series Configura-
tion Memories” application note, available on the Atmel web site (www.atmel.com).
