#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)
