D.5.5 ADC Control Register 1
SCAN — Scan Mode Selection
MULT — Multichannel Conversion
S8CM — Select Eight-Conversion Sequence Mode

ADCTL1 — ADC Control Register 1
15
ADCTL1 is used to initiate an A/D conversion and to select conversion modes and a
conversion channel or channels. It can be read or written at any time. A write to
ADCTL1 initiates a conversion sequence. If a conversion sequence is already in
progress, a write to ADCTL1 aborts it and resets the SCF and CCF flags in the ADC
status register.
Length of conversion sequence(s) is determined by S8CM.
Length of conversion sequence(s) is determined by S8CM.
This bit determines the number of conversions in a conversion sequence.
displays the different ADC conversion modes.
RESET:
0 = Single conversion
1 = Continuous conversions
0 = Conversion sequence(s) run on a single channel selected by [CD:CA].
1 = Sequential conversions of four or eight channels selected by [CD:CA].
0 = Four-conversion sequence
1 = Eight-conversion sequence
