#### 13.2.7 pinnumber attribute ¶

This attribute is the pin number (i.e. like `GND` is `7` on 74 TTL). All pins must have a pinnumber=# attribute attached to the pin object.

You can have numbers or letters for the value. This attribute should be visible with the value only visible. You also need a pinseq attribute (pinseq attribute).

Examples:

    pinnumber=1
    pinnumber=13
    pinnumber=A0

This attribute replaces the obsolete pin#=# attribute.
