#define NutInitSysIrq (   )

Value: INTC.ISCR.BIT.IRQ0SC = 0; \ INTC.IPRA.BIT._IRQ0 = 0; Low level sensing interrupt; Very important! High poriority; CKE1-0 in SCR, default setting; C/A# in SMR, default setting; P95DDR, default setting: P9DDR = B_1100_0000; SCI1.SMR.BIT.CA = 0;

#define NIC_IO_BASE   (0x800000UL + 0x300UL)

IO base address of RTL chip.

#define NicIntIsEnabled (   )     (INTC.IER.BIT.IRQ0E == 1)

Check Nic Int is set or not

#define NicDisableInt (   )     INTC.IER.BIT.IRQ0E = 0

Disable Nic Interruption

#define NicEnableInt (   )     INTC.IER.BIT.IRQ0E = 1

Enable Nic Interruption

#define NicMcu16bitBus (   )     BSC.ABWCR.BIT.ABW4 = 0

Switch MCU data bus (area 4) into 16 bit mode

#define NicMcu8bitBus (   )     BSC.ABWCR.BIT.ABW4 = 1

Switch MCU data bus (area 4) into 8 bit mode

#define RTL_SIGNAL   sig_INT0

interruption signal handler of RTL_SIGNAL_BIT.
