| 4 | CRC status (1=Error, 0=OK)? |
| 15-5 | ? |
| 19-16 | Transfer size (0=0 bytes, 1=4 bytes, 2=0x10 bytes, 0x40, 0x200, 0x400, 0x800, 0x1000, 8=0x4000 bytes) |

| 31-16 | Total data blocks to write to FIFO - 1 |
CTRCARD_SECCNT
| BIT | DESCRIPTION |
|---|---|

| 9-8 | Key index |
| 15 | Latch seed |
CTRCARD_CMD
Specifies the 16-byte command to send. The command is split into 32-bit words, and stored as least significant word first, with each word itself in big-endian format.
