• IO713_D0: this signal is sampled by the FPGA at each rising edge of CCLK. It is the DATA ouput of the

EEPROM memory,

• CON: this signal shall be first maintained to a low logic level by an external master component. The

configuration download starts immediately and CCLK is directly output. Once the ATF280F has sampled the

CON pin to low during three CCLK periods, it starts to drive the CON pin to a low logic level. Then the external

master component shall release the CON signal,

• IO303_INIT: this signal is internally pulled-up and is used as an error monitoring pin. Refer to Data Link

Protection

section for serial configuration,

• IO259_LDC: the Low During Configuration is driven to a low logic level,

• IO265_HDC: the High During Configuration is driven to a high logic level,

• RESETN: this signal is an input which immediately reset the configuration logic to a Manual Reset lifephase.

[Run]: Once configured, the ATF280F enters in Run lifephase. In this lifephase, the loaded application runs and its own

lifephases are taken into account. This lifephase is entered few CCLK cycles after the ATF280F has sensed the

postamble, it then releases the configuration interface signals and all multiplexed signals are set to their GPIO function:

• M0, M1, M2: these signals remain inputs and are not used anymore,

• CCLK: this signal is an input with pull-up and is not used anymore,

• IO713_D0: this signal becomes a User I/O and takes its application configuration,

• CON: this signal is released to a high logic level,

• IO303_INIT: this signal becomes a User I/O and takes its application configuration,

• IO259_LDC: this signal becomes a User I/O and takes its application configuration,

• IO265_HDC: this signal becomes a User I/O and takes its application configuration,

• RESETN: this signal is an input which immediately reset the configuration logic to a Manual Reset lifephase.
