DACK1 Pin (pin 18)
For pin 18, V
CC5
has been changed to the DACK1 pin. To use DMA channel 1 for ML60852A, connect
the DACK1 pin to the DMA controller. If channel 1 is not to be used, no change is required. However,
since the DACK1 pin is active-High after system reset, be sure to set the DMA enable bit of the
DMA1CON register to "0".

ALE Pin

ALE/PUCTL Pin (pin 23)
For use in multiplexed mode (ADSEL = “H”), no change is required.
To use the pull-up control function in separate mode (ADSEL = “L”), connect the ALE/PUCTL pin to a
1.5 k
Ω
pull-up resistor.
Leave this pin open if the pull-up control function is not used.

–DREQ1 Pin (pin 25)
This pin is an input pin on the ML60851 but it is an output pin on the ML60852A. Therefore, connect it
to the DMA controller when DMA channel 1 is used.
Leave this pin open if channel 1 is not used.
