Need help with my code

Hi
i wrote the MISO-MISO, SCK-SCK, MOSI-MOSI but now is that how i assigned the rest of the pins for CE, CSN and IRQ of the nRF24L01
#include "C8051F120.h"
// Peripheral specific initialization functions,
// Called from the Init_Device() function
void SPI_Init()
{
SFRPAGE = SPI0_PAGE;
SPI0CFG = 0x40;
SPI0CN = 0x01;
}

void Port_IO_Init()
{
// P0.0 - SCK (SPI0), Open Drain,Digital
// P0.1 - MISO (SPI0), Open Drain,Digital
// P0.2 - MOSI (SPI0), Open-Drain,Digital
// P0.3 - NSS (SPI0), Open-Drain,Digital
// P0.4 - Unassigned, Open-Drain,Digital
// P0.5 - Unassigned, Open-Drain,Digital
// P0.6 - Unassigned, Open-Drain,Digital
// P0.7 - Unassigned, Open-Drain,Digital

// P1.0 - Unassigned, Open-Drain,Digital
// P1.1 - Unassigned, Open-Drain,Digital
// P1.2 - Unassigned, Open-Drain,Digital
// P1.3 - Unassigned, Open-Drain,Digital
// P1.4 - Unassigned, Open-Drain,Digital
// P1.5 - Unassigned, Open-Drain,Digital
// P1.6 - Unassigned, Open-Drain,Digital
// P1.7 - Unassigned, Open-Drain,Digital

// P2.0 - Unassigned, Open-Drain,Digital
// P2.1 - Unassigned, Open-Drain,Digital
// P2.2 - Unassigned, Open-Drain,Digital
// P2.3 - Unassigned, Open-Drain,Digital
// P2.4 - Unassigned, Open-Drain,Digital
// P2.5 - Unassigned, Open-Drain,Digital
// P2.6 - Unassigned, Open-Drain,Digital
// P2.7 - Unassigned, Open-Drain,Digital

// P3.0 - Unassigned, Open-Drain,Digital
// P3.1 - Unassigned, Open-Drain,Digital
// P3.2 - Unassigned, Open-Drain,Digital
// P3.3 - Unassigned, Open-Drain,Digital
// P3.4 - Unassigned, Open-Drain,Digital
// P3.5 - Unassigned, Open-Drain,Digital
// P3.6 - Unassigned, Open-Drain,Digital
// P3.7 - Unassigned, Open-Drain,Digital

SFRPAGE = CONFIG_PAGE;
XBR0 = 0x02;
XBR2 = 0x40;
}

void Interrupts_Init()
{
EIE1 = 0x01;
}

// Initialization function for device,
// Call Init_Device() from your main program
void Init_Device(void)
{
SPI_Init();
Port_IO_Init();
Interrupts_Init();
}
Put aside the source code i prepared to solder the SCK, MISO, MOSI, CSN as i found out that using any port pin then the IRQ is connected to so which mean i need set the pin for int0. Just to confirm? Tks in advance.
