Operating Modes
MOTOROLA
11.3 User Mode
In user 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 input-only
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. User
mode is entered on the rising edge of RESET if the IRQ pin is within
normal operating range.
