ADC Connections if the ADC Is Not Used
It is recommended to keep the connections for the analog power pins, even if the ADC is not used.
Following is a summary of how the ADC pins should be connected, if the ADC is not used in an
application:
VDD1A18/VDD2A18 – Connect to VDD
VDDA2, VDDAIO – Connect to VDDIO
VSS1AGND/VSS2AGND, VSSA2, VSSAIO – Connect to VSS
ADCLO – Connect to VSS
ADCREFIN – Connect to VSS
ADCREFP/ADCREFM – Connect a 100-nF cap to VSS
ADCRESEXT – Connect a 20-k
resistor (very loose tolerance) to VSS.
ADCINAn, ADCINBn - Connect to VSS
When the ADC is not used, be sure that the clock to the ADC module is not turned on to realize power
savings.
When the ADC module is used in an application, unused ADC input pins should be connected to analog
ground (VSS1AGND/VSS2AGND)
NOTE
ADC parameters for gain error and offset error are specified only if the ADC calibration
routine is executed from the Boot ROM. See Section 4.7.3 for more information.
4.7.2
ADC Registers
The ADC operation is configured, controlled, and monitored by the registers listed in Table 4-6.

(1)
The registers in this column are Peripheral Frame 2 Registers.
(2)
The ADC result registers are dual mapped. Locations in Peripheral Frame 2 (0x7108-0x7117) are 2 wait-states and left justified.
Locations in Peripheral frame 0 space (0x0B00-0x0B0F) are 1 wait-state for CPU accesses and 0 wait state for DMA accesses and right
justified. During high speed/continuous conversion use of the ADC, use the 0 wait-state locations for fast transfer of ADC results to user
memory.
