Normal. DMA request pins cannot be used for GPIO.
Multiplexed. If external multiplexer is used, several of the DMA Request signals
can be used for GPIO.
Normal. DMA acknowledge pins cannot be used for GPIO.
Encoded. If external priority decoder is used, several of the DMA Acknowledge
signals can be used for GPIO.
