Example 5a

// Example 5a: Pushbutton Switches

#include <hidef.h> /* common defines and macros */

#include <mc9s12dp256.h> /* derivative information */

#include "main_asm.h" /* interface to the assembly module */

#pragma LINK_INFO DERIVATIVE "mc9s12dp256b"

void main(void) {

PLL_init(); // set system clock frequency to 24 MHz

seg7_enable(); // enable 7-segment display

ATD0DIEN = 0x18; // enable S1 and S2

while(1){

if((PORTAD0 & 0x10) == 0)

seg7dec(1);

else

seg7_off();

if((PORTAD0 & 0x08) == 0)

seg7dec(2);

else

seg7_off();

}

}
