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.

Reserved bits [31:1] - Read Only
RO 0x0
0 ACK_GEN_CALL
ACK General Call.
When set to 1, DW_apb_i2c responds with a ACK
(by asserting ic_data_oe) when it receives a General Call.
Otherwise, DW_apb_i2c responds with a NACK
(by negating ic_data_oe).
Default Reset value: 0x1, but can be hardcoded by setting the
IC_DEFAULT_ACK_GENERAL_CALL configuration parameter.
Value Description
0x0 Generate NACK for General Call
0x1 Generate ACK for a General Call
RW 0x1
