DMA_ADC Address Register
The DMA_ADC Address Register, shown in Table 84, points to a block of the Register
File to store the ADC conversion values displayed in Table 83. This register contains the
seven most significant bits of the 12-bit Register File addresses. The five least significant
bits are calculated from the ADC analog input number (5-bit base address is equal to twice
the ADC analog input number). The 10-bit ADC conversion data is stored as two bytes
with the most significant byte of the ADC data stored at the even-numbered Register File
address.
Table 83 provides an example of the Register File addresses if the DMA_ADC Address
Register contains the value 72H.
