(3) Starting A/D conversion
Normal A/D conversion can be initiated programmatically by setting ADMOD0<ADS> to 1.
Highest-priority
ADMOD2<HPADCE> to 1. Normal A/D conversion is performed in one of the four operating
modes as specified with ADMOD0<2:1>. Highest-priority A/D conversion is only performed in
channel-fixed single conversion mode. A/D conversion can also be activated by a hardware start
source, which is specified with ADMOD4<ADHS> for normal A/D conversion and
ADMOD4<HADHS> for highest-priority A/D conversion. When the ADHS or HADHS bit is set to
0, A/D conversion is triggered by a falling edge on the ADTRG pin. When the bit is set to 1,
normal A/D conversion is triggered by INTTA0 from 8-bit timer 0 and highest-priority A/D
conversion is triggered by INTTA1 from 8-bit timer 1. A/D conversion can still be started
programmatically if hardware start is enabled.
is set to 1, indicating that normal A/D conversion is in progress. When highest-priority A/D
conversion starts, the highest-priority A/D conversion busy flag (ADMOD2<ADBFHP>) is set to 1,
indicating that highest-priority A/D conversion is in progress, with the normal A/D conversion busy
flag and end flag (EOCFN) holding the values they had before highest-priority A/D conversion
starts.
conversion. Restarting normal A/D conversion cancels the current conversion. However, if all
necessary sampling operations have been completed for the current conversion, the conversion
result is stored before A/D conversion is restarted.
conversion is restarted when the start condition for the resource is satisfied during normal A/D
conversion. The current conversion is cancelled when normal A/D conversion is restarted. However,
if all necessary sampling operations have been completed for the current conversion, the conversion
result is stored before A/D conversion is restarted.
conversion is stored in the conversion result registers, after which highest-priority A/D conversion
starts, that is, A/D conversion for the channel specified with ADMOD2<3:0> (channel-fixed single
conversion) starts. Once the result of highest-priority conversion is stored in ADREGSP, normal
A/D conversion is resumed following the last conversion for which the result was stored.
