Registers
| Offset | Size | Description |
|---|---|---|
| 0x00 | 4 | Port mode (1=out, 0=in) (1 bit each port) |
| 0x04 | 4 | Port read (1=low, 0=high?) (1 bit each port) |
| 0x08 | 4 | Port set (1 bit each port) |
| 0x0C | 4 | Port clear (1 bit each port) |
| 0x14 | 4 | Interrupt mode (2 bits) for interrupts 0-15 |
| 0x18 | 4 | Interrupt mode (2 bits) for interrupts 16-31 |
| 0x34 | 4 | Port read latched? (1=low, 0=high?) (1 bit each port) |
It looks like +0x10,+0x14,+0x18,+0x1C,+0x20 are related to interrupt enable, and +0x38,+0x3C,+0x40,+0x44,+0x48 to interrupt ack.
