IC_DMA_CR

         Name: DMA Control Register
Size: 2 bits
Address Offset: 0x88
Read/Write Access: Read/Write
This register is only valid when DW_apb_i2c is configured
with a set of DMA Controller interface signals (IC_HAS_DMA = 1).
When DW_apb_i2c is not configured for DMA operation, this register
does not exist and writing to the register's address has no
effect and reading from this register address will return zero.
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.

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.
