5.3.1.2 Manual Reset in mode 1

The chronogram described here after presents the sequence of ATF280F from a Manual Reset until Idle. This is the

global overview of ATF280F Manual Reset sequence. At the end of this sequence, the ATF280F remains unconfigured

and is ready for configuration download in slave mode.

Figure 5-9.

ATF280F: Manual Reset in mode 1

Notes:

1. This line shows the different lifephase viewable in life cycle diagram described in OperatingModes /

Lifephases

section,

“MS” means Mode Sampling lifephase,

“CCE” means Clear Cycle End.

[Manual Reset]: During the Manual Reset lifephase, the ATF280F starts to drive the signal regarding the configuration

download interfaces as defined below. This phase is entered when the RESETN pin is activated. The end of this

lifephase is marked by the rising edge of IO303_INIT pin. During Manual Reset lifephase, the Clear Cycle operation

(ended by CCE in the figure above) starts immediately and is performed in approximatively 2 ms. If the RESETN pin is

activated during less than the 2 ms required for the Clear Cycle operation, the ATF280F remains in Manual Reset until

CCE time:

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

• CCLK: this signal is internally pulled-up,

• IO713_D0: this signal is internally pulled-up,

• CON: this signal is driven to a low logic level,
