2.4 CE/MPU Communication

Figure 7 shows the functional relationship between the CE and the MPU. The CE is controlled by the

MPU via shared registers in the I/O RAM and RAM. The CE outputs two interrupt signals to the MPU to

indicate the CE is actively processing data and the CE is updating data to the output region of the RAM.
