Table 9-6 summarizes events that cause ISP interrupts.
Event and Register(1) | Description |
---|---|
ISP5_IRQENABLE_SET_i[[31] OCP_ERR_IRQ | An interface port error has been received on the ISP master port. |
ISP5_IRQENABLE_SET_i[29] IPIPE_INT_DPC_RNEW1 | HD interrupt signal to indicate the need to renew the defect pixel correction (DPC) table with new entries. The second 128 entries in the DPC table must be updated when this event triggers. This event is triggered when the 255th entry in the look-up table (LUT) is used. This interrupt is not synchronous to the HD signal. |
ISP5_IRQENABLE_SET_i[28] IPIPE_INT_DPC_RNEW0 | VD interrupt signal to indicate the need to renew the DPC table with new entries. The first 128 entries in the DPC table must be updated when the event triggers. This event is triggered when the 127th entry in the LUT is used. This interrupt is not synchronous to the HD signal. |
ISP5_IRQENABLE_SET_i[27] IPIPE_INT_DPC_INI | Interrupt to signal the need to initialize the DPC table. The DPC table contains two tables of 128 entries. When this signal is used, software must ensure that the 256 table entries are updated with the DPC information. |
ISP5_IRQENABLE_SET_i[25] IPIPE_INT_EOF | End of frame interrupt signal |
ISP5_IRQENABLE_SET_i[24] H3A_INT_EOF | End of frame interrupt signal |
ISP5_IRQENABLE_SET_i[22] RSZ_INT_EOF1 | See Section 9.1.3, ISS Register Manual, and Section 9.3.4, ISS ISP Register Manual. |
ISP5_IRQENABLE_SET_i[23] RSZ_INT_EOF0 | See Section 9.1.3, ISS Register Manual, and Section 9.3.4, ISS ISP Register Manual. |
ISP5_IRQENABLE_SET_i[19] RSZ_FIFO_IN_BLK_ERR | See Section 9.1.3, ISS Register Manual, and Section 9.3.4, ISS ISP Register Manual. |
ISP5_IRQENABLE_SET_i[18] RSZ_FIFO_IN_OVF | See Section 9.1.3, ISS Register Manual, and Section 9.3.4, ISS ISP Register Manual. |
ISP5_IRQENABLE_SET_i[17] RSZ_INT_CYC_RZB | See Section 9.1.3, ISS Register Manual, and Section 9.3.4, ISS ISP Register Manual. |
ISP5_IRQENABLE_SET_i[16] RSZ_INT_CYC_RZA | See Section 9.1.3, ISS Register Manual, and Section 9.3.4, ISS ISP Register Manual. |
ISP5_IRQENABLE_SET_i[15] RSZ_INT_DMA | See Section 9.1.3, ISS Register Manual, and Section 9.3.4, ISS ISP Register Manual. |
ISP5_IRQENABLE_SET_i[14] RSZ_INT_LAST_PIX | See Section 9.1.3, ISS Register Manual, and Section 9.3.4, ISS ISP Register Manual. |
ISP5_IRQENABLE_SET_i[13] RSZ_INT_REG | See Section 9.1.3, ISS Register Manual, and Section 9.3.4, ISS ISP Register Manual. |
ISP5_IRQENABLE_SET_i[12] H3A_INT | Interrupt generated by the AF and AE/AWB blocks inside the H3A module. It indicates the end of processing a frame and is active high for one configuration bus clock cycle. |
ISP5_IRQENABLE_SET_i[11] AF_INT | AF inside generates an interrupt at the end of processing frame; a third interrupt is generated at the same time as the last process to finish. |
ISP5_IRQENABLE_SET_i[10] AEW_INT | AEW inside generates an interrupt at the end of processing frame; a third interrupt is generated at the same time as the last process to finish. |
ISP5_IRQENABLE_SET_i[9] IPIPEIF_IRQ | IPIPEIF module interrupt is generated at the start position of a frame and is active high for one configuration bus clock cycle. |
ISP5_IRQENABLE_SET_i[8] IPIPE_INT_HST | IPIPE module interrupt is generated when histogram is done. |
ISP5_IRQENABLE_SET_i[7] IPIPE_INT_BSC | IPIPE module interrupt is generated when boundary signal calculation is done. |
ISP5_IRQENABLE_SET_i[6] IPIPE_INT_DMA | IPIPE module interrupt is issued when the SDRAM transfer of boxcar is done. At this time, IPIPE EOF is sent to buffer logic. |
ISP5_IRQENABLE_SET_i[5] IPIPE_INT_LAST_PIX | IPIPE module interrupt is issued when the last pixel of a frame comes into IPIPE. |
ISP5_IRQENABLE_SET_i[4] IPIPE_INT_REG | IPIPE module interrupt is issued when the register update of the module is allowed. |
ISP5_IRQENABLE_SET_i[3] ISIF_INT_3 | See Section 9.1.3, ISS Register Manual, and Section 9.3.4, ISS ISP Register Manual. |
ISP5_IRQENABLE_SET_i[2] ISIF_INT_2 | See Section 9.1.3, ISS Register Manual, and Section 9.3.4, ISS ISP Register Manual. |
ISP5_IRQENABLE_SET_i[1] ISIF_INT_1 | See Section 9.1.3, ISS Register Manual, and Section 9.3.4, ISS ISP Register Manual. |
