9 Which line of C code is a friendly way to set Port B bit 2
assuming this pin has already been initialized as an output
GPIO_PORTB_DATA_R = 0x00;
GPIO PORTB DATA R = 0x02;
|
-
GPIO PORTB DATA R = 0x04;
|
GPIO_PORTB_DATA_R |= 0x02;
GPIO PORTB DATA R |= 0x04;
|
GPIO_PORTB_DATA_R &= 0x02;
GPIO PORTB DATA R &= 0x04;
GPIO PORTB DATA R &= ~0x02;
GPIO PORTB DATA R &= ~0x04;
