Signal Description
2.24
The MCF5253 complies with the IEEE 1149.1A JTAG testing standard. The JTAG test pins are
multiplexed with background debug pins. See
for details.
2.25
These signals configure the MCF5253 and provide interface signals to the external system.
2.25.1
Asserting RSTI causes the MCF5253 to enter reset exception processing. When RSTI is recognized, the
data bus is tri-stated.
2.25.2
MCF5253 includes on-chip crystal oscillator. The crystal must be connected between CRIN and CROUT.
An externally generated clock signal can also be used and should be connected directly to the CRIN pin.
2.26
To exit power down mode, apply a LOW level to the WAKEUP/GPIO21 input pin.
