1.奇奇怪怪的CLA

dsp的学习历程远比我的单片机学习例程痛苦。

今天说下CLA配置的问题。

以下是CLA的官方部分配置代码，这一切都很普通，也很正常，但是让鄙人调试难受的一点是，此&claTask1中断函数赋值的时候，只有EALLOW,但是没有EDIS,只要加了EDIS就不行

void CLA_initCpu1Cla1(void)
{//// Suppressing #770-D conversion from pointer to smaller integer// The CLA address range is 16 bits so the addresses passed to the MVECT// registers will be in the lower 64KW address space. Turn the warning// back on after the MVECTs are assigned addresses//
#pragma diag_suppress=770EALLOW;Cla1Regs.MVECT1 = (uint16_t)(&Cla1Task1);Cla1Regs.MVECT2 = (uint16_t)(&Cla1Task2);Cla1Regs.MVECT3 = (uint16_t)(&Cla1Task3);Cla1Regs.MVECT4 = (uint16_t)(&Cla1Task4);Cla1Regs.MVECT5 = (uint16_t)(&Cla1Task5);Cla1Regs.MVECT6 = (uint16_t)(&Cla1Task6);Cla1Regs.MVECT7 = (uint16_t)(&Cla1Task7);Cla1Regs.MVECT8 = (uint16_t)(&Cla1Task8);
#pragma diag_warning=770//// Enable the IACK instruction to start a task on CLA in software// for all  8 CLA tasks. Also, globally enable all 8 tasks (or a// subset of tasks) by writing to their respective bits in the// MIER register//Cla1Regs.MCTL.bit.IACKE = 1;Cla1Regs.MIER.all = 0x00FF;//// Configure the vectors for the end-of-task interrupt for all// 8 tasks//PieVectTable.CLA1_1_INT = &cla1Isr1;PieVectTable.CLA1_2_INT = &cla1Isr2;PieVectTable.CLA1_3_INT = &cla1Isr3;PieVectTable.CLA1_4_INT = &cla1Isr4;PieVectTable.CLA1_5_INT = &cla1Isr5;PieVectTable.CLA1_6_INT = &cla1Isr6;PieVectTable.CLA1_7_INT = &cla1Isr7;PieVectTable.CLA1_8_INT = &cla1Isr8;//// Enable CLA interrupts at the group and subgroup levels//PieCtrlRegs.PIEIER11.all = 0xFFFF;IER |= (M_INT11 );
}
