1: The data time-out set by DTOCYC and DTOMUL in HSMCI_DTOR has been exceeded. Cleared by reading in the
HSMCI_SR register.
• CSTOE: Completion Signal Time-out Error
0: No error.
1: The completion signal time-out set by CSTOCYC and CSTOMUL in HSMCI_CSTOR has been exceeded. Cleared by
reading in the HSMCI_SR register. Cleared by reading in the HSMCI_SR register.
• BLKOVRE: DMA Block Overrun Error
0: No error.
1: A new block of data is received and the DMA controller has not started to move the current pending block, a block over-
run is raised. Cleared by reading in the HSMCI_SR register.
• DMADONE: DMA Transfer done
0: DMA buffer transfer has not completed since the last read of HSMCI_SR register.
1: DMA buffer transfer has completed.
• FIFOEMPTY: FIFO empty flag
0: FIFO contains at least one byte.
1: FIFO is empty.
• XFRDONE: Transfer Done flag
0: A transfer is in progress.
1: Command register is ready to operate and the data bus is in the idle state.
• ACKRCV: Boot Operation Acknowledge Received
0: No Boot acknowledge received since the last read of the status register.
1: A Boot acknowledge signal has been received. Cleared by reading the HSMCI_SR register.
• ACKRCVE: Boot Operation Acknowledge Error
0: No error
1: Corrupted Boot Acknowledge signal received.
• OVRE: Overrun
0: No error.
1: At least one 8-bit received data has been lost (not read). Cleared when sending a new data transfer command.
When
