+# Set a bit
+```c
+// Set one bit high at position "bit" in input and store to output
+output = input | (1 << bit);
+// Shorthand
+variable |= (1 << bit);
+```
+
+# Clear a bit
+```c
+// Clear one bit high at position "bit" in input and store to output
+output = input & ~(1 << bit);
+// Shorthand
+variable &= ~(1 << bit);
+```
+
+# Toggle a bit
+```c
+// Clear one bit high at position "bit" in input and store to output
+output = x ^ (1 << bit);
