CC2510Fx / CC2511Fx
ADCCON3 (0xB6) - ADC Control 3
Bit Field Name Reset R/W Description
7:6 EREF[1:0] 00
R/W Selects reference voltage used for the extra conversion
00
Internal 1.25V reference
01
External reference on AIN7 pin (only CC2510Fx)
10
VDD on the AVDD pin
11
External reference on AIN6 - AIN7 differential input (only CC2510Fx)
5:4 EDIV[1:0]
00
R/W Sets the decimation rate used for the extra conversion. The decimation rate also
determines the resolution and time required to complete the conversion.
00
64 dec rate (7 bits resolution)
01
128 dec rate (9 bits resolution)
10
256 dec rate (10 bits resolution)
11
512 dec rate (12 bits resolution)
3:0 ECH[3:0]
0000
R/W Extra channel select. An extra conversion will be triggered by writing to these bits.
If they are written while the ADC is running, the conversion will take place as soon
as the sequence has completed. If the bits are written while the ADC is not
running, the conversion will take place immediately after this register has been
updated.
The bits are automatically cleared when the extra conversion has finished.
