Operating Modes
MOTOROLA
6.3 Single-Chip Mode
In single-chip mode, the address and data buses are not available
externally, but there are two 8-bit input/output (I/O) ports and one 4-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 pin
is within normal operating range.
Refer to Figure 1-2 for the single-chip user mode pinout diagram.
6.4 Self-Check Mode
The self-check mode provides an internal check to determine if the
device is functional.
6.5 Low-Power Modes
The following subsections provide a description of the low-power modes.
6.5.1 Stop Mode
The STOP instruction places the MCU in its lowest power-consumption
mode. In stop mode, the internal oscillator is turned off, halting all
internal processing, including timer (and COP watchdog timer)
operation.
During stop mode, the I bit in the CCR is cleared to enable external
interrupts. All other registers, including the bits in the TCSR, and
memory remain unaltered. All input/output lines remain unchanged. The
processor can be brought out of stop mode only by an external interrupt
or RESET.
The STOP instruction can be disabled by a mask option. When disabled,
the STOP instruction causes a chip reset.
