A channel is considered enabled if CH[n].PSELP is set. If more than one channel, CH[n], is enabled, the ADC enters Scan mode.
In Scan mode, one SAMPLE task will trigger one conversion per enabled channel. The time it takes to sample all channels is given by the following equation:
Total time < Sum(CH[x].tACQ+tCONV), x=0..enabled channelsA DONE event signals that one sample has been taken.
In this mode, the RESULTDONE event signals has the same meaning as DONE when no oversampling takes place. Both events may occur before the actual values have been transferred into RAM by EasyDMA.
The following figure shows an example of the placement of results in Data RAM, with an even RESULT.MAXCNT. In this example, channels 1, 2, and 5 are enabled, all others are disabled.
The following figure shows an example of the placement of results in Data RAM, with an odd RESULT.MAXCNT. In this example, channels 1, 2 and, 5 are enabled, all others are disabled. The last 32-bit word is populated only with one 16-bit result.
