nRF24LE1 Preliminary Product Specification
21.3.8
The ADC is interfaced to the MCU through five registers; ADCCON1 , ADCCON2 , ADCCON3 , ADCDATH and
ADCDATL . ADCCON1 , ADCCON2 and ADCCON3 contain configuration settings and status bits. The conver-
sion result is contained in the ADCDATH and ADCDATL registers.
