MCF5282 External Signals
14.2.12.7 DMA Timer 3 Input (DTIN3)
The DMA timer 3 input (DTIN3) can be programmed as an input that causes events to
occur in DMA timer 3. This can either clock the event counter or provide a trigger to the
timer value capture logic. This pin can also be configured as GPIO PTC3, secondary
function URTS1, or secondary function URTS0.
14.2.12.8 DMA Timer 3 Output (DTOUT3)
The programmable DMA timer output (DTOUT0) pulse or toggle on various timer events.
This pin can also be configured as GPIO PTC2, secondary function URTS1, or secondary
function URTS0.
14.2.13 Analog-to-Digital Converter Signals
These pins provide the analog inputs to the QADC.
The PQA and PQB pins may also be used as general purpose digital I/O.
14.2.13.1 QADC Analog Input (AN0/ANW)
This PQB signal is the direct analog input AN0. When using external multiplexing this pin
can also be configured as multiplexed input ANW.
This pin can also be configured as GPIO PQB0.
14.2.13.2 QADC Analog Input (AN1/ANX)
This PQB signal is the direct analog input AN1. When using external multiplexing this pin
can also be configured as multiplexed input ANX.
This pin can also be configured as GPIO PQB1.
14.2.13.3 QADC Analog Input (AN2/ANY)
This PQB signal is the direct analog input AN2. When using external multiplexing this pin
can also be configured as multiplexed input ANY.
This pin can also be configured as GPIO PQB2.
14.2.13.4 QADC Analog Input (AN3/ANZ)
This PQB signal is the direct analog input AN3. When using external multiplexing this pin
can also be configured as multiplexed input ANZ.
This pin can also be configured as GPIO PQB3.
14.2.13.5 QADC Analog Input (AN52/MA0)
This PQA signal is the direct analog input AN52. When using external multiplexing this
