Type Aliases

AIS_R

Field AIS reader - Abnormal Interrupt Summary. Logical OR of the following: IDSTS[2] : Fatal Bus Interrupt, IDSTS[4] : DU bit Interrupt. Only unmasked bits affect this bit. This is a sticky bit and must be cleared each time a corresponding bit that causes AIS to be set is cleared. Writing 1 clears this bit.

AIS_W

Field AIS writer - Abnormal Interrupt Summary. Logical OR of the following: IDSTS[2] : Fatal Bus Interrupt, IDSTS[4] : DU bit Interrupt. Only unmasked bits affect this bit. This is a sticky bit and must be cleared each time a corresponding bit that causes AIS to be set is cleared. Writing 1 clears this bit.

CES_R

Field CES reader - Card Error Summary. Indicates the status of the transaction to/from the card, also present in RINTSTS. Indicates the logical OR of the following bits: EBE : End Bit Error; RTO : Response Timeout/Boot Ack Timeout; RCRC : Response CRC; SBE : Start Bit Error; DRTO : Data Read Timeout/BDS timeout; DCRC : Data CRC for Receive; RE : Response Error. Writing 1 clears this bit. The abort condition of the IDMAC depends on the setting of this CES bit. If the CES bit is enabled, then the IDMAC aborts on a response error.

CES_W

Field CES writer - Card Error Summary. Indicates the status of the transaction to/from the card, also present in RINTSTS. Indicates the logical OR of the following bits: EBE : End Bit Error; RTO : Response Timeout/Boot Ack Timeout; RCRC : Response CRC; SBE : Start Bit Error; DRTO : Data Read Timeout/BDS timeout; DCRC : Data CRC for Receive; RE : Response Error. Writing 1 clears this bit. The abort condition of the IDMAC depends on the setting of this CES bit. If the CES bit is enabled, then the IDMAC aborts on a response error.

DU_R

Field DU reader - Descriptor Unavailable Interrupt. This bit is set when the descriptor is unavailable due to OWNER bit = 0 (DES0[31] = 0). Writing 1 clears this bit.

DU_W

Field DU writer - Descriptor Unavailable Interrupt. This bit is set when the descriptor is unavailable due to OWNER bit = 0 (DES0[31] = 0). Writing 1 clears this bit.

FBE_CODE_R

Field FBE_CODE reader - Fatal Bus Error Code. Indicates the type of error that caused a Bus Error. Valid only when the Fatal Bus Error bit IDSTS[2] is set. This field does not generate an interrupt. 001: Host Abort received during transmission; 010: Host Abort received during reception; Others: Reserved.

FBE_CODE_W

Field FBE_CODE writer - Fatal Bus Error Code. Indicates the type of error that caused a Bus Error. Valid only when the Fatal Bus Error bit IDSTS[2] is set. This field does not generate an interrupt. 001: Host Abort received during transmission; 010: Host Abort received during reception; Others: Reserved.

FBE_R

Field FBE reader - Fatal Bus Error Interrupt. Indicates that a Bus Error occurred (IDSTS[12:10]) . When this bit is set, the DMA disables all its bus accesses. Writing 1 clears this bit.

FBE_W

Field FBE writer - Fatal Bus Error Interrupt. Indicates that a Bus Error occurred (IDSTS[12:10]) . When this bit is set, the DMA disables all its bus accesses. Writing 1 clears this bit.

FSM_R

Field FSM reader - DMAC FSM present state. 0: DMA_IDLE (idle state); 1: DMA_SUSPEND (suspend state); 2: DESC_RD (descriptor reading state); 3: DESC_CHK (descriptor checking state); 4: DMA_RD_REQ_WAIT (read-data request waiting state); 5: DMA_WR_REQ_WAIT (write-data request waiting state); 6: DMA_RD (data-read state); 7: DMA_WR (data-write state); 8: DESC_CLOSE (descriptor close state).

FSM_W

Field FSM writer - DMAC FSM present state. 0: DMA_IDLE (idle state); 1: DMA_SUSPEND (suspend state); 2: DESC_RD (descriptor reading state); 3: DESC_CHK (descriptor checking state); 4: DMA_RD_REQ_WAIT (read-data request waiting state); 5: DMA_WR_REQ_WAIT (write-data request waiting state); 6: DMA_RD (data-read state); 7: DMA_WR (data-write state); 8: DESC_CLOSE (descriptor close state).

NIS_R

Field NIS reader - Normal Interrupt Summary. Logical OR of the following: IDSTS[0] : Transmit Interrupt, IDSTS[1] : Receive Interrupt. Only unmasked bits affect this bit. This is a sticky bit and must be cleared each time a corresponding bit that causes NIS to be set is cleared. Writing 1 clears this bit.

NIS_W

Field NIS writer - Normal Interrupt Summary. Logical OR of the following: IDSTS[0] : Transmit Interrupt, IDSTS[1] : Receive Interrupt. Only unmasked bits affect this bit. This is a sticky bit and must be cleared each time a corresponding bit that causes NIS to be set is cleared. Writing 1 clears this bit.

R

Register IDSTS reader

RI_R

Field RI reader - Receive Interrupt. Indicates the completion of data reception for a descriptor. Writing 1 clears this bit.

RI_W

Field RI writer - Receive Interrupt. Indicates the completion of data reception for a descriptor. Writing 1 clears this bit.

TI_R

Field TI reader - Transmit Interrupt. Indicates that data transmission is finished for a descriptor. Writing 1 clears this bit.

TI_W

Field TI writer - Transmit Interrupt. Indicates that data transmission is finished for a descriptor. Writing 1 clears this bit.

W
