Description
End of conversion Cleared when both ADCH and ADCL has been
read. If a new conversion is completed before the previous data
has been read, the EOC bit will remain high.
0 conversion not complete
1 conversion completed
Start conversion. Read as 1 until conversion has completed
0 no conversion in progress
1 start a conversion sequence if ADCCON1.STSEL = “11” and
no sequence is running.
5:4 _STSEL[1:0] 11
R/W Start select. Selects which event that will start a new conversion
sequence.
00
External trigger on P2_0 pin.
01
Full speed. Do not wait for triggers.
10

11
R/W Controls the 16 bit random number generator. When written 01,
the setting will automatically return to 00 when operation has
completed.
00
Normal operation. (13x unrolling)
01
Clock the LFSR once (no unrolling).
10
Reserved
11
Stopped. Random number generator is turned off.
R/W Reserved. Always set to 11.
