RESET
The M52210DEMO provides a RESET button, with indicator, to reset the target device. The
MCF52210 also supports several internal resets. Consult the MCF522235 RM for details on all
supported resets.
RESET SWITCH
The RESET switch provides a method to apply an asynchronous reset to the MCU and is con-
nected directly to the RSTI* input on the MCU. Pressing the RESET switch holds RSTI* low
until the switch is released. An external pull-up on the RSTI* line prevents spurious resets al-
lowing normal operation.
RESET INDICATOR
The RESET LED is connected to the RSTO* output on the MCF52210. This LED lights when
the MCU is in RESET and remains on for the duration of an asserted RSTO* signal. RSTO*
may also be used as a general-purpose output to drive the RESET LED as needed.
LOW-POWER MODES
The MCF52210 supports several operational modes designed to reduce power consumption.
Low-power modes include Wait, Doze, Stop, and Halt.
