Peripheral clock. DW_apb_i2c runs on this clock and is used to clock transfers in standard, fast, and high-speed mode. Note: ic_clk frequency must be greater than or equal to pclk frequency. The configuration parameter IC_CLK_TYPE indicates the relationship between pclk and ic_clk. It can be asynchronous (1) or identical (0).
