47 / 100 page ![]() 47/100 PSD4256G6V This is preliminary information on a new product now in development or undergoing evaluation. Details are subject to change without notice. MCU BUS INTERFACE The “no-glue logic” MCU Bus Interface block can be directly connected to most popular 8-bit and 16- bit MCUs and their control signals. Key MCUs, with their bus types and control signals, are shown in Table 34. The MCU interface type is specified using the PSDsoft. Table 34. 16-bit MCUs and Their Control Signals Note: 1. Unused CNTL2 pin can be configured as CPLD input. Other unused pins (PD3-PD0, PF3-PF0) can be configured for other I/O func- tions. 2. ALE/AS input is optional for MCUs with a non-multiplexed bus. 3. This configuration is for MC68HC812A4_EC at 5MHz, 3V only.
