MCF52110 Family Configurations

1.2.21 Reset

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:

• External reset input

• Power-on reset (POR)

• Watchdog timer

• Phase locked-loop (PLL) loss of lock / loss of clock

• Software

• Low-voltage detector (LVD)

• JTAG

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 GPIO

Nearly all pins on the MCF52110 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 Part Numbers and Packaging

This product is RoHS-compliant. Refer to the product page at freescale.com or contact your sales office for up-to-date RoHS
