so this will set them to output
        let p_row1 = (0x50000000 + 0x754) as *mut u32;
        let p_col1 = (0x50000000 + 0x770) as *mut u32;
        unsafe {
            *p_row1 = 0x0000_0001;
            *p_col1 = 0x0000_0001;
        }
and then step two I'll write to the OUTSET and it looks like i need to set the nth bit so in this case 21 and 28
