Legend:
R = Readable bit
-n = Value at POR
HC = Hardware Clearable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
bit 15-8
bit 7
bit 6
bit 5-0
Unimplemented: Read as ‘0’
ACEN: Accumulator Enable bit⁽¹⁾
1 = Accumulation is enabled; sample and convert the current sample list entry on trigger event and add
to the contents of ACRESH/L
0 = The accumulation process has not started or is complete (cleared in hardware when accumulation
COUNTx bits decrement to zero)
ACIE: Accumulator Interrupt Enable bit
1 = An interrupt event is generated when the accumulator decrements to zero
0 = Accumulator interrupt events are disabled
Unimplemented: Read as ‘0’
Note 1: To avoid unexpected or erroneous results, do not write to ACCONH or ACCONL while ACEN is set.

TBLSEL<5:0>: Pointer to ADTBLn Used to Select ANxx Channel to be Accumulated bits
The ANxx channel is designated by the ADTBLn register (where n = TBLSEL<5:0> value).
COUNT<7:0>: Accumulations to be Completed Counter bits
Decrements on each accumulated sample. Before starting the accumulation process, preload this
COUNTx bits field with the number of samples to accumulate (ex: To get a 9 sample sum, load COUNT
with 9). Starting with a COUNT value of 0 will result in 256 samples being accumulated.
