45 / 173 page ![]() BlueNRG-1 Functional details DocID028866 Rev 1 45/173 Bit Field name Reset RW Description 30 HTIF7 0x0 R Channel 7 half transfer flag. This bit is set by hardware. It is cleared by software writing 1 to the corresponding bit in the IFCR register. 0: No half transfer (HT) event on channel 7. 1: A half transfer (HT) event occurred on channel 7. 31 TEIF7 0x0 R Channel 7 transfer error flag. This bit is set by hardware. It is cleared by software writing 1 to the corresponding bit in the IFCR register. 0: No transfer error (TE) event on channel 7. 1: A transfer error (TE) occurred on channel 7. Table 39: DMA - IFCR register description: address offset DMA_BASE_ADDR+0x04 Bit Field name Reset RW Description 0 CGIF0 0x0 W Channel 0 global interrupt flag.
