How using external interrupts instead of keyboard interrupt (KIN0:1)

Hi,

Actually I have an embedded system without keyboard in my PCB.
The program is write in C and use polling for checking 8 externals periphericals but now I need to use polling only for 6 of them and so I must use external interrupt for the 2 others which are connected to ports P1.0 and P1.1 but these
ports are for Keyboard Interrupt.

Can you help me please to find my way for using 2 simple externals interrupts
on ports P1.0 and P1.1 instead of external Keyboard Interrupts.

My looping code is:

void micro (void)
{

if (!Detect_P2 && !Detect_P3 && !Detect_P4 && !Detect_P5 && !Detect_P6 && !Detect_P7 && !Detect_P8)
{Mic_Mute_PA = 0x01;}
else {Mic_Mute_PA = 0x00;}

if (P1_0 == 0)   //using it with external INTERRUPT
{
Unmute_PA(); //291107 pour un bon gong le faire avant d'entrer dans MicDriver_ON()
mic_driver_2 ();}        //Driver on
else { mic_driver_off_2  (); } //Driver off


if (P1_1 == 0)   //using it with external INTERRUPT
{
Unmute_PA();
radio_on_2 ();}        //RAD on
else { rad_off_2 (); } //RAD off


if (P3_3 == 0)
{in1_on_2 ();}        //IN1 on
else { in1_off_2  (); } //IN1 off

if (P3_4 == 0)
{
in2_on_2 ();}        //IN2 on
else { in2_off_2  (); } //IN2 off

if (P3_5 == 0)
{in3_on_2 ();}        //IN3 on
else { in3_off_2  (); } //IN3 off

if (P1_2 == 0)
{
aux_on_2 ();}        //AUX on
else { aux_off_2  (); } //AUX off

if (P1_3 == 0)
{
mic_guide_2 ();
}
else
{ mic_guide_off_2 ();
}

}

Thank you
