|---|---|
| 15-0 | Total data blocks to read from FIFO - 1 |
| 31-16 | Total data blocks to write to FIFO - 1 |
CTRCARD_SECCNT[edit]
| Bit | Description |
|---|---|
| 2 | Latch key index |
| 9-8 | Key index |
| 15 | Latch seed |
CTRCARD_CMD[edit]
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.
