Need help about exception vectors table.

[tjulsm]

I am a student that is studying the MCF52233 demo, But I just can't find the detail of Exception vectors assignments of vectors from 64-255. Who can tell me ,just where to find the correlative document about it. Thanks!

Have a look in the reference manual, in the Interrupt Controller section.

Hi

Yes all details are there (section 15.3.6.1) but you will also have to match the interrupt masks to the exceptions (IC_IMRL_0, IC_IMRH_0, IC_IMRL_1, IC_IMRH_1). Here is a list of the exceptions - and gaps in the list are reserved exception locations (IRQs are also known as Edge Ports):

    #define IRQ1_VECTOR         0x41    #define IRQ2_VECTOR         0x42    #define IRQ3_VECTOR         0x43    #define IRQ4_VECTOR         0x44    #define IRQ5_VECTOR         0x45    #define IRQ6_VECTOR         0x46    #define IRQ7_VECTOR         0x47    #define SW_WD_VECTOR        0x48    #define DMA0_VECTOR         0x49    #define DMA1_VECTOR         0x4a    #define DMA2_VECTOR         0x4b    #define DMA3_VECTOR         0x4c    #define UART0_VECTOR        0x4d    #define UART1_VECTOR        0x4e    #define UART2_VECTOR        0x4f    #define IIC_VECTOR          0x51    #define QSPI_VECTOR         0x52    #define DTIM0_VECTOR        0x53    #define DTIM1_VECTOR        0x54    #define DTIM2_VECTOR        0x55    #define DTIM3_VECTOR        0x56    #define FEC_TX_F_VECTOR     0x57    #define FEC_TX_B_VECTOR     0x58    #define FEC_TX_UND_VECTOR   0x59    #define FEC_COLL_VECTOR     0x5a    #define FEC_RX_F_VECTOR     0x5b    #define FEC_RX_B_VECTOR     0x5c    #define FEC_MII_VECTOR      0x5d    #define FEC_LATE_VECTOR     0x5e    #define FEC_HB_VECTOR       0x5f    #define FEC_STOP_VECTOR     0x60    #define FEC_BERR_VECTOR     0x61    #define FEC_BAB_TX_VECTOR   0x62    #define FEC_BAB_RX_VECTOR   0x63    #define EPHY_VECTOR         0x64    #define GPT_TOF_VECTOR      0x69    #define GPT_PAIF_VECTOR     0x6a    #define GPT_PAOVF_VECTOR    0x6b    #define GPT_C0F_VECTOR      0x6c    #define GPT_C1F_VECTOR      0x6d    #define GPT_C2F_VECTOR      0x6e    #define GPT_C3F_VECTOR      0x6f    #define PMM_LVDF_VECTOR     0x70    #define ADC_ADCA_VECTOR     0x71    #define ADC_ADCB_VECTOR     0x72    #define ADC_ADCINT_VECTOR   0x73    #define PWM_INT_VECTOR      0x74    #define RNGA_VECTOR         0x75    #define PIT0_VECTOR         0x77    #define PIT1_VECTOR         0x78    #define CFM_CBEIF_VECTOR    0x7b    #define CFM_CCIF_VECTOR     0x7c    #define CFM_PVIF_VECTOR     0x7d    #define CFM_AEIF_VECTOR     0x7e    #define RTC_VECTOR          0x7f    #define CAN0_VECTOR         0x88    #define CAN1_VECTOR         0x89    #define CAN2_VECTOR         0x8a    #define CAN3_VECTOR         0x8b    #define CAN4_VECTOR         0x8c    #define CAN5_VECTOR         0x8d    #define CAN6_VECTOR         0x8e    #define CAN7_VECTOR         0x8f    #define CAN8_VECTOR         0x90    #define CAN9_VECTOR         0x91    #define CAN10_VECTOR        0x92    #define CAN11_VECTOR        0x93    #define CAN12_VECTOR        0x94    #define CAN13_VECTOR        0x95    #define CAN14_VECTOR        0x96    #define CAN15_VECTOR        0x97    #define CANERR_VECTOR       0x98    #define CANBOFF_VECTOR      0x99    #define IRQ8_VECTOR         0xa0    #define IRQ9_VECTOR         0xa1    #define IRQ10_VECTOR        0xa2    #define IRQ11_VECTOR        0xa3    #define IRQ12_VECTOR        0xa4    #define IRQ13_VECTOR        0xa5    #define IRQ14_VECTOR        0xa6    #define IRQ15_VECTOR        0xa7

 

Also take a look at the uTasker project. It is completely free for educational use, including full support. It includes all code that you require and a M5223X simulator which will enable testing and easier learning on a PC without the need for hardware. It has its own forum for most up to date information about its development (http://www.uTasker.com/forum/ )
