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.

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.
