MCF52223 Family Configurations
1.2.21
The reset controller determines the source of reset, asserts the appropriate reset signals to the system, and keeps track of what
caused the last reset. There are seven sources of reset:
Control of the LVD and its associated reset and interrupt are managed by the reset controller. Other registers provide status flags
indicating the last source of reset and a control bit for software assertion of the RSTO pin.
1.2.22
Nearly all pins on the MCF52223 have general purpose I/O capability and are grouped into 8-bit ports. Some ports do not use
all eight bits. Each port has registers that configure, monitor, and control the port pins.
1.2.23
This product is RoHS-compliant. Refer to the product page at
