Preliminary data sheet
when the output line number is equal to the line number specified in the register at
0x10E1F0[11:0]
An unwanted situation can arise when shadowing starts (as a result of the trigger)
before the user has finished programming a complete sequence of register changes.
To prevent this from happening, the complete register reprogramming must be
followed by a “FINISH” which should really trigger the shadowing. The “FINISH” is
activated via rewriting a value of “1” to the LayerN_Enable, which originally has value
“1”. This is sometimes called rehitting the LayerN_Enable bit. By making use of this
mechanism, any “UNFINISHED” programming will only be ready for shadowing when
the LayerN_Enable is rehit. Figure 13 below depicts the intended programming
procedure for QVCP.
Remark: Once the shadowing is complete, the Layer upload bit is set again.
