Operating Modes
MOTOROLA
The mode of operation is also determined whenever the internal
computer operating properly (COP) watchdog timer resets the MCU.
When the COP timer expires, the voltage applied to the IRQ/V
PP
pin
controls the mode of operation while the voltage applied to PD7/TCAP is
ignored. The voltage applied to PD7/TCAP during the last rising edge on
RESET is stored in a latch and used to determine the mode of operation
when the COP watchdog timer resets the MCU.
3.3 User Mode
The user 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 and are
not available externally. User mode is entered on the rising edge of
RESET if the IRQ/V
PP
pin is within the normal operating voltage range.
The pinout for the user mode is shown in
Figure 3-1
.
Figure 3-1. User Mode Pinout
In the user mode, there is an 8-bit I/O port, a second 8-bit I/O port shared
with the analog-to-digital (A/D) subsystem, one 3-bit I/O port shared with
the serial input/output port (SIOP), and a 3-bit port shared with the 16-bit
timer subsystem, which includes one general-purpose I/O pin.
