For C coding embedded systems,For software coding, without using if-else equation, and only using shift operations(bitwise), how would you code based on software requirements as stated from picture?

3.3 Design 1 3.3.1 Specifications: This design runs in a 3.3V system. 3.3.2 Requirements: Hardware Design 1 has one input and one output. O Input: PB4 connects to switch named swl, positive logic. o Output: PB1 connects to LED1, positive logic. Software When swl is not pressed & held, LED1 turns off. When swl is pressed & held at the same time, LED1 turns on. 3.3 Design 1 3.3.1 Specifications: This design runs in a 3.3V system. 3.3.2 Requirements: Hardware Design 1 has one input and one output.
