Once configured, autoconvert mode initiates with one
ADC Convert command. Conversions continue at the
rate selected by the ADC Autoconvert bits (see Table 4)
until disabled by writing to the ADC Control register. The
Autoconvert mode can run only in the normal or fast
power-down modes. The autoconvert function must be
disabled to use burst mode or DPIO CONVST mode.
When writing to the ADC Control register in fast power-
down mode with autoconvert disabled, acquisition
begins on the 1st rising ADC clock edge after
CS tran-
sitions high, and ends after the programmed number of
clock cycles. The conversion completes a minimum 14
clock cycles after acquisition ends. When autoconvert
is enabled, an additional three ADC clock cycles are
added prior to acquisition to allow the ADC to wake up.
See Figures 19 and 20 for timing diagrams.
