The ATD control register 5 is used to select the conversion modes, the
conversion channel(s), and initiate conversions.
Read or write any time. Writes to the ATD control registers initiate a new
conversion sequence. If a conversion sequence is in progress when a
write occurs, that sequence is aborted and the SCF and CCF bits are
reset.
S8CM — Select 8 Channel Mode
SCAN — Enable Continuous Channel Scan
MULT — Enable Multichannel Conversion
Freescale Semiconductor, Inc.
When a conversion sequence is initiated by a write to the ATDxCTL
register, the user has a choice of performing a sequence of four (or
eight, depending on the S8CM bit) conversions or continuously
performing four (or eight) conversion sequences.
For More Information On This Product,
