Application with Co4011
To enable the programming condition chose an
identifier that forces the Pins ID0 and ID1 to low
level. For example identifiers ID= 3, 7, 0x0B, 0x0F …
might be used. Close the jumpers Jx and Jy.
For optimised programming adapter design, the
programming adapter should close the jumpers Jx
and Jy directly by plugging the adaptor into the
application board.
For normal operation mode the programming
adapter must be removed.
