// The state machine then waits for updt to be set. // When the updt bit is set, the interface asserts u_enb low on a // falling-edge of clk and addr/data is latched on the next falling edge // (rd_clk should be on the rising-edge). The state machine writes // data to t...

Due to the structure of the I2Cinterface, the core uses a 5*SCL clock internally. The prescale register must beprogrammed to this 5*SCL frequency (minus 1). Change the value of the prescaleregister only when the ‘EN’ bit is cleared. Example: wb_clk_i = 32MHz, desired SCL = 100...

3 verilog HDL 代码设计 由于I2C 总线传输协议可知,I2C 在传输过程中存在着几个固定的状态,因此我们采用同步状态机来设计I2C 模块。主状态机共有5个状态:空闲(Idle ),开始(Start ),发送数据(Tx ),接收数据(Rx ),停止(Stop )。图3 I2C 模块主状态机状态转移图 Idle :I2C 总线处在空闲状态。Start :当...
