The host error interrupt (HOST_PEND) will be asserted, if enabled when a host error is detected during transmit or receive CPDMA transactions. The host error interrupt is intended for software debug, and is cleared by a warm reset or a system reset. The raw and masked host interrupt status can be read by reading the CPDMA_DMA_INTSTAT_RAW and CPDMA_DMA_INTSTAT_MASKED registers, respectively.
The transmit host error conditions are:
The receive host error conditions are:
The HOST_PEND is enabled by setting to 1 the HOST_ERR_INTMASK in the CPDMA_DMA_INTMASK_SET register. The host error interrupt is disabled by setting to 1 the appropriate bit in the CPDMA_DMA_INTMASK_CLEAR register.
