Remote Update WYSIWYG ATOM
An alternative to using the altremote_update megafunction is to
directly instantiate the remote update WYSIWYG atom. This atom should
be included in the factory configuration and any application
configuration image to access the remote configuration shift registers.
When implementing the atom, you should consider following:
1. Only one atom can be used in the circuit; more than one gives a
no-fit.
2. All signals for the cell must be connected. The clock port (CLK) must
be connected to a live cell. The others can be constant V
CC
or GND.
3. The pgmout port must be connected and must feed PGM[2.0]
output pins (it cannot be connected to anything else but output
pins).
4. The Quartus II software reserves RUnLU as an input pin, and you
must connect it to V
CC
.
