50 / 152 page  Operating Modes General Release Specification MC68HC705CT4 — Rev. 2.0 50 Operating Modes MOTOROLA 6.3 Single-Chip Mode In single-chip mode, the address and data buses are not available externally, but there are three 8-bit input/output (I/O) ports and one 7-bit I/O port. This mode allows the MCU to function as a self-contained microcontroller, with maximum use of the pins for on-chip peripheral functions. All address and data activity occurs within the MCU. Single- chip mode is entered on the rising edge of RESET if the IRQ/VPP pin is within normal operating range. Figure 6-1.
