DADH = ADH
Not Bit Addressable
Bit
When LADJ = 0, bits 7–0 of the ADC result are found in bits 7–0 of DADL.
When LADJ = 1, bits 1–0 of the ADC result are found in bits 7–6 of DADL. Bits 5–0 are cleared to zero.
When LADJ = 0, bits 9–8 of the ADC result are found in bits 1–0 of DADH. Bits 7–2 are signed extended copies of bit 1.
When LADJ = 1, bits 9–2 of the ADC result are found in bits 7–0 of DADH.
