3.2.2.1 Pin programming scheme
The programming pins Con_Sel_0 (LSB) to Con_Sel_4 (MSB) are used to represent the configuration
index, whereas Con_Sel_5 is used as the parity bit (even parity). See also Figure
and Table
2
on this page. Depending on the selected programming pin combination, a switch configuration
is loaded from one of 16 possible positions.
• If the dip switch is set to position ON, the pin is connected to Ground on the connector.
• If the dip switch is set to position OFF, the pin is not connected at all on the connector.
Table
3
on the current page lists the valid programming pin combinations that are possible for the default
configuration (Con_Sel_0 = OFF).
To select a programming pin combination for the actual/backup configuration, set Con_Sel_0 to ON.
