Timing Table Description: ON-LINE phase
1^st step: Acquisition
- MCLK [INPUT] must be connectedwith the external synchronization signal.
- OFL [INPUT] must be set low to enable the acquisition/elaborationphase of W.A.R.P..
- FIN [INPUT] must be set high for at least 1clock period to start the acquisition phase. OFL must already
be low since at least 4 clock periods before providing a FIN pulse. FIN duration must be in the range
[1clock,2clock periods]. FIN pulse mustn’t coincide with NP transitions.
- NP [OUTPUT] will remain low during the acquisition phase.
- The input data must be sent to I0-I6 after OFL has been set low and FIN has been set high. Data situated
in I0-I6 are stored into its internal registers at each next rising edge of the MCLK.
- After the current inputs have been acquired, the NP [OUTPUT] high signal informs that the elaboration
phase can start. This information is provided thanks to the configuration stored in the program memory.
