3 System Memory Controller (SMC) As long as the slave device receives an acknowledge, it will continue to increment the word address and serially clock out sequential data words. The I 2 C sequential read operation is terminated when the I 2 C master controller does not respond with an acknowledge. This can be accomplished by setting only the i2_enbl bit in the I 2 C Control Register before receiving the last data word. A stop sequence then must be transmitted to the slave device by first setting the i2_stop and i2_enbl bits in the I 2 C Control Register and then writing a dummy data (data=don’t care) to the I 2 C Transmitter Data Register. The I 2 C Status Register must now be polled to test i2_cmplt bit for the operation-complete status. The stop sequence will relinquish the ASIC master’s possession of the I 2 C bus. Figure 3-9 shows the suggested software flow diagram for programming the I 2 C sequential read operation. 3-32 <strong>Computer</strong> Group Literature Center Web Site
