8-bit microcontroller with accelerated two-clock 80C51 core
8.4.4 Auto scan, continuous conversion mode
Any combination of the eight input channels can be selected for conversion. A conversion
of each selected input will be performed and the result placed in the result register pair
which corresponds to the selected input channel. The user may select whether an
interrupt, if enabled, will be generated after either the first four conversions have occurred
or all selected channels have been converted. If the user selects to generate an interrupt
after the four input channels have been converted, a second interrupt will be generated
after the remaining input channels have been converted. After all selected channels have
been converted, the process will repeat starting with the first selected channel. Additional
conversion results will again cycle through the eight result register pairs, overwriting the
previous results. Continuous conversions continue until terminated by the user.
8.4.5 Dual channel, continuous conversion mode
This is a variation of the auto scan continuous conversion mode where conversion occurs
on two user-selectable inputs. The result of the conversion of the first channel is placed in
the result register pair, AD0DAT0R and AD0DAT0L. The result of the conversion of the
second channel is placed in result register pair, AD0DAT1R and AD0DAT1L. The first
channel is again converted and its result stored in AD0DAT2R and AD0DAT2L. The
second channel is again converted and its result placed in AD0DAT3R and AD0DAT3L.
An interrupt is generated, if enabled, after every set of four or eight conversions (user
selectable).
8.4.6 Single step mode
This special mode allows ‘single-stepping’ in an auto scan conversion mode. Any
combination of the eight input channels can be selected for conversion. After each
channel is converted, an interrupt is generated, if enabled, and the A/D waits for the next
start condition. May be used with any of the start modes.
8.5 Conversion start modes
8.5.1 Timer triggered start
An A/D conversion is started by the overflow of Timer 0. Once a conversion has started,
additional Timer 0 triggers are ignored until the conversion has completed. The Timer
triggered start mode is available in all ADC operating modes.
8.5.2 Start immediately
Programming this mode immediately starts a conversion. This start mode is available in all
ADC operating modes.
8.5.3 Edge triggered
An A/D conversion is started by rising or falling edge of P1.4. Once a conversion has
started, additional edge triggers are ignored until the conversion has completed. The edge
triggered start mode is available in all ADC operating modes.
