This attribute is used to give each pin an unique number or sequence.
All pins must have a pinseq=# attribute attached to the pin
object. This attribute should be hidden. This attribute is used
extensively by lepton-schematic and lepton-netlist.
In some backends (especially the SPICE backend), lepton-netlist will
output pins in the order of increasing pin sequence. The sequence
numbers start at 1 and should increase without skipping any numbers.
This attribute is not the pin number (i.e. device pin numbers, like
GND is 7 on TTL). For pin numbers see the pinnumber attribute
(pinnumber attribute).
Examples:
pinseq=1 pinseq=2 pinseq=3
This attribute replaces the obsolete pin#=# attribute.
