ic_dma_cr
Name: DMA Control Register
The register is used to enable the DMA Controller interface operation.
There is a separate bit for transmit and receive. This can be programmed
regardless of the state of IC_ENABLE.
Module Instance | Base Address | Register Address |
---|---|---|
i_i2c_0_i2c | 0xFFC02200 | 0xFFC02288 |
i_i2c_1_i2c | 0xFFC02300 | 0xFFC02388 |
Offset: 0x88
Access: RW
Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.
