Construct UART Data Frame with Parity Bit

Code

#include <stdio.h>
#include <stdint.h>

typedef struct {
    uint8_t parity_enable : 1;
    uint8_t parity_type   : 1;
    uint8_t reserved      : 6;
} UART_Control;

uint8_t create_uart_frame(uint8_t data, UART_Control *ctrl) {
    uint8_t temp;
    uint8_t count=0;
    uint8_t i=0;
    while(i<7){
    temp = (data>>i)&1;
    if(temp == 1){
        count++;
    
    }
    i++;
    }
     data =  data & 0x7F;
     if(ctrl->parity_enable == 0){
        return data;
     }

int parity_bit;

     if(ctrl->parity_type ==0){
        parity_bit = (count % 2 == 0) ? 0 : 1;
     }
     else{
        parity_bit = (count % 2 == 0) ? 1 : 0;
     }
    
    return (parity_bit << 7) | data;
}

int main() {
    uint8_t data;
    scanf("%hhu", &data);  // 7-bit input

    uint8_t parity_enable, parity_type;
    scanf("%hhu %hhu", &parity_enable, &parity_type);

    UART_Control ctrl;
    ctrl.parity_enable = parity_enable;
    ctrl.parity_type = parity_type;

    uint8_t frame = create_uart_frame(data, &ctrl);
    printf("frame = 0x%02X", frame);

    return 0;
}
