40.7.17 ADACC

ADC Accumulator Register⁽¹⁾

See the Computation Operation section for more details.

Important: This register contains signed two’s complement accumulator value and the upper unused bits contain copies of the sign bit.

Note:

This register can only be written when GO = 0.
The individual bytes in this multibyte register can be accessed with the following register names:
- ADACCU: Accesses the upper byte ADACC[17:16]
- ADACCH: Accesses the high byte ADACC[15:8]
- ADACCL: Accesses the low byte ADACC[7:0]

Name:	ADACC
