| Offset | Size | Description |
|---|---|---|
| 0x004 | 4 | bits[1:0]: Video mode (0 = Progressive, 0b11 = Interlaced) |
| 0x00C | 4 | bits[28:16]: vtotal, bits[12:0]: (vtotal + 1) >> 1
|

| 0x030 | 4 | bits[31:16] = VSW
|
| 0x050 | 4 | Interrupts ack/clear (read = triggered interrupts, write = clear interrupt) |
| 0x054 | 4 | Interrupt enable mask (bit 1 = some interrupt) |
| 0x410 | 4 | DSI Command read FIFO status (bit 5 = Read FIFO empty) |
| 0x430 | 4 | DSI Command read FIFO |
| 0x500 | 4 | DSI Command FIFO |
| 0x510 | 4 | Another command FIFO (used to write the packet for command reads) |
| 0x838 | 4 | DSI auto clock configuration (1 = only HS clock, 0 = auto gate when data in LP) |
