ADMOD0
(0x FF00_4D04)
Analog/Digital Converter
17.1 Control Register
The A/D converter is controlled by A/D mode control registers (ADnMOD0, ADnMOD1, ADnMOD2,
ADnMOD3 and ADnMOD4: n=A, B). Results of A/D conversion are stored in A/D conversion result registers
ADAREG0 through ADAREG3 and ADBREG0 through ADBREG3. Results of top-priority conversion are
stored in ADAREGSP and ADBREGSP.
Fig. 17.2 through Fig. 17.4 show the registers related to the A/D converter.
