Bits 11:8 DELAY: Delay between 2 sampling phases
These bits are set and cleared by software. These bits are used in dual interleaved modes.
Refer to Table 98 for the value of ADC resolution versus DELAY bits values.
Note: Software is allowed to write these bits only when the ADCs are disabled (ADCAL=0,
JADSTART=0, ADSTART=0, ADSTP=0, ADDIS=0 and ADEN=0).
Bits 7:5 Reserved, must be kept at reset value.
Bits 4:0 DUAL[4:0]: Dual ADC mode selection
These bits are written by software to select the operating mode.
All the ADCs independent:
00000: Independent mode
00001 to 01001: Dual mode, master and slave ADCs working together
00001: Combined regular simultaneous + injected simultaneous mode
00010: Combined regular simultaneous + alternate trigger mode
00011: Combined Interleaved mode + injected simultaneous mode
00100: Reserved
00101: Injected simultaneous mode only
00110: Regular simultaneous mode only
00111: Interleaved mode only
01001: Alternate trigger mode only
All other combinations are reserved and must not be programmed
Note: Software is allowed to write these bits only when the ADCs are disabled (ADCAL=0,
JADSTART=0, ADSTART=0, ADSTP=0, ADDIS=0 and ADEN=0).
