Analog-to-digital converter (ADC)
Bits 19:16 SQ5[3:0]: 5th conversion of the sequence
These bits are programmed by software with the channel number (0...14) assigned to the 8th
conversion of the sequence. 0b1111 indicates end of the sequence.
When 0b1111 (end of sequence) is programmed to the lower sequence channels, these bits are
ignored.
Refer to SQ8[3:0] for a definition of channel selection.
Note: The software is allowed to write this bit only when ADSTART = 0 (which ensures that no
conversion is ongoing).
Bits 15:12 SQ4[3:0]: 4th conversion of the sequence
These bits are programmed by software with the channel number (0...14) assigned to the 8th
conversion of the sequence. 0b1111 indicates end of the sequence.
When 0b1111 (end of sequence) is programmed to the lower sequence channels, these bits are
ignored.
Refer to SQ8[3:0] for a definition of channel selection.
Note: The software is allowed to write this bit only when ADSTART = 0 (which ensures that no
conversion is ongoing).
Bits 11:8 SQ3[3:0]: 3rd conversion of the sequence
These bits are programmed by software with the channel number (0...14) assigned to the 8th
conversion of the sequence. 0b1111 indicates end of the sequence.
When 0b1111 (end of sequence) is programmed to the lower sequence channels, these bits are
ignored.
Refer to SQ8[3:0] for a definition of channel selection.
Note: The software is allowed to write this bit only when ADSTART = 0 (which ensures that no
conversion is ongoing).
Bits 7:4 SQ2[3:0]: 2nd conversion of the sequence
These bits are programmed by software with the channel number (0...14) assigned to the 8th
conversion of the sequence. 0b1111 indicates end of the sequence.
When 0b1111 (end of sequence) is programmed to the lower sequence channels, these bits are
ignored.
Refer to SQ8[3:0] for a definition of channel selection.
Note: The software is allowed to write this bit only when ADSTART = 0 (which ensures that no
conversion is ongoing).
Bits 3:0 SQ1[3:0]: 1st conversion of the sequence
These bits are programmed by software with the channel number (0...14) assigned to the 8th
conversion of the sequence. 0b1111 indicates end of the sequence.
When 0b1111 (end of sequence) is programmed to the lower sequence channels, these bits are
ignored.
Refer to SQ8[3:0] for a definition of channel selection.
Note: The software is allowed to write this bit only when ADSTART = 0 (which ensures that no
conversion is ongoing).
