channels have been converted. The process will repeat starting with the rst selected
channel. Additional conversion results will again cycle through the four result
registers, overwriting the previous results. Continous conversions continue until
terminated by the user.
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 rst channel is placed in result register, AD1DAT0.
The result of the conversion of the second channel is placed in result register,
AD1DAT1. The rst channel is again converted and its result stored in AD1DAT2. The
second channel is again converted and its result placed in AD1DAT3. An interrupt is
generated, if enabled, after every set of four conversions (two conversions per
channel).
Single step mode: This special mode allows ‘single-stepping’ in an auto scan
conversion mode. Any combination of the four 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.
8.9.4
Conversion start modes
Timer triggered start: An A/D conversion is started by the overow 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 A/D operating
modes.
Start immediately: Programming this mode immediately starts a conversion. This
start mode is available in all A/D operating modes.
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 A/D operating
modes.
