Signal Description
2.13
There is a 3-line subcode interface on the MCF5253. This 3-line subcode interface allows the device to
format and transmit subcode in EIAJ format to a CD channel encoder device. The three signals are
described in
2.14
The ADOUT signal on the ADOUT/SCLK4/GPIO58 pin provides the reference voltage in PWM format.
Therefore this output requires an external integrator circuit (resistor/capacitor) to convert it to a DC level
to be input to the ADREF pin.
The six AD inputs are each fed to their own comparator the reference input to each (ADREF) is then
multiplexed as only one AD comparison can be made at any one time.
2.15
The device has a versatile flash card interface that supports both SecureDigital and MemoryStick cards.
The interface can either support one SecureDigital or two MemoryStick cards. No mixing of card types is
possible.

To use the ADINx as General Purpose inputs (rather than the analog
function) it is necessary to generate a fixed comparator voltage level of
VDD/2. This is accomplished by a potential divider network connected to
the ADREF pin. However in portable applications where stand-by power
consumption is important, the current taken by the divider network (in
stand-by mode) can be excessive. Therefore it is possible to generate a
VDD/2 voltage by selecting SCLK4 output mode and feeding this clock
signal (which is 50% duty cycle) through an external integration circuit.
This generates a voltage level equal to VDD/2, however when stand-by
mode is selected it is disabled.
