Three address spaces (Program Memory, Register File, and Expanded Register File [ERF]), support a wide range of memory configurations. Through the ERF, the designer has access to three additional control registers that provide extra peripheral devices, I/O ports, and register addresses. The rest of the ERF is not physically implemented and is open for future expansion. For applications demanding powerful I/O capabilities, the Z86C3X/C40's dedicated input and output lines are grouped into three and four ports, respectively, and are configurable under software control to provide timing, status signals, or parallel I/O. Two on-chip counter/timers, with a large number of selectable modes, offload the system of administering real-time tasks such as counting/timing and I/O data munications. With ROM/ROMless selectivity, the Z86C40 provides both external...
