Protocol Control
| LCTL | LED Control 0 (LCTL_0): LED off 1 (LCTL_1): LED on |
| DTW | Data Transfer Width 0 (DTW_0): 1-bit mode 1 (DTW_1): 4-bit mode 2 (DTW_2): 8-bit mode |
| D3CD | DATA3 as Card Detection Pin 0 (D3CD_0): DATA3 does not monitor Card Insertion 1 (D3CD_1): DATA3 as Card Detection Pin |
| EMODE | Endian Mode 0 (EMODE_0): Big Endian Mode 1 (EMODE_1): Half Word Big Endian Mode 2 (EMODE_2): Little Endian Mode |
| CDTL | Card Detect Test Level 0 (CDTL_0): Card Detect Test Level is 0, no card inserted 1 (CDTL_1): Card Detect Test Level is 1, card inserted |
| CDSS | Card Detect Signal Selection 0 (CDSS_0): Card Detection Level is selected (for normal purpose). 1 (CDSS_1): Card Detection Test Level is selected (for test purpose). |
| DMASEL | DMA Select 0 (DMASEL_0): No DMA or Simple DMA is selected 1 (DMASEL_1): ADMA1 is selected 2 (DMASEL_2): ADMA2 is selected |
| SABGREQ | Stop At Block Gap Request 0 (SABGREQ_0): Transfer 1 (SABGREQ_1): Stop |
| CREQ | Continue Request 0 (CREQ_0): No effect 1 (CREQ_1): Restart |
| RWCTL | Read Wait Control 0 (RWCTL_0): Disable Read Wait Control, and stop SD Clock at block gap when SABGREQ bit is set 1 (RWCTL_1): Enable Read Wait Control, and assert Read Wait without stopping SD Clock at block gap when SABGREQ bit is set |
| IABG | Interrupt At Block Gap 0 (IABG_0): Disabled 1 (IABG_1): Enabled |
| RD_DONE_NO_8CLK | RD_DONE_NO_8CLK |
| WECINT | Wakeup Event Enable On Card Interrupt 0 (WECINT_0): Disable 1 (WECINT_1): Enable |
| WECINS | Wakeup Event Enable On SD Card Insertion 0 (WECINS_0): Disable 1 (WECINS_1): Enable |
| WECRM | Wakeup Event Enable On SD Card Removal 0 (WECRM_0): Disable 1 (WECRM_1): Enable |
| BURST_LEN_EN | BURST length enable for INCR, INCR4 / INCR8 / INCR16, INCR4-WRAP / INCR8-WRAP / INCR16-WRAP 1 (BURST_LEN_EN_1): Burst length is enabled for INCR |
| NON_EXACT_BLK_RD | NON_EXACT_BLK_RD 0 (NON_EXACT_BLK_RD_0): The block read is exact block read. Host driver doesn’t need to issue abort command to terminate this multi-block read. 1 (NON_EXACT_BLK_RD_1): The block read is non-exact block read. Host driver needs to issue abort command to terminate this multi-block read. |
