The semicolon has no function of either a period or a comma, but it is an intermediary between them. In other words, there is no total or brief pause, but a moderation between the two.
It is used:
To separate items in an enumeration (common in laws):
Art. 1º The lease of urban property is regulated by the provisions of this Law.
Single paragraph. They are still regulated by the Civil Code and special laws:
a) the locations:
1. properties owned by the Union, the States of the Municipalities, their autarchies and public foundations;
2. autonomous parking spaces or vehicle parking spaces;
3. of spaces for advertising.
To separate very long coordinated sentences or those that already have a comma:
“Sometimes we also have the comfort of knowing that something that was said by chance helped someone to reconcile with themselves or with their life; to dream a little, to feel a desire to do something good." (Ruben Braga)
It can also replace the comma, in order to have a little longer break. This happens before the adversative conjunctions (however, but, however, however, nevertheless):
1. I want to hang out with you more; because a couple needs to have good friendships.
2. Tomorrow is test day; but I haven't started studying yet.
