The RS Latch, also known as the SR Latch, is a sequential logic gate with 4 inputs and 2 outputs. The name stands for Set Reset Latch. This is the fundamental gate used to create digital memory, as it can store the state of 1 bit (on or off).

The RS Latch has 2 input and 4 outputs. When placed, on the ground, the left and right function both as inputs and outputs, while the front and back are just outputs. The left and right sides are the selectors while the front and back are state outputs.
The whole idea of the RS Latch is as follows. There are 2 states, each one consisting of a selector and a state output. The selectors control which of the 2 states is active. When a state is selected, its output will remain on until the other one is selected. Selecting the same state multiple times has no effect.
The RS Latch has 2 different modes. In mode 1, the selectors also function as state outputs, meaning that if their respective state output is active, they themselves will also emit a signal. In mode 2, the selectors do not function as state outputs.
A shift-right-click with a screwdriver can change the settings on the gate. When placed, the RS Latch is on mode 1. The first click will flip which side (front or back) each selector input is tied to. A second click will change it to mode 2. A third click will flip mode 2. After that, it will reset to unflipped mode 1.
|v4.0.0||Added the RS Latch.|
|v4.5.9||Fixed bug that caused the state to stick when in flipped modes|
