ADMOD0
(0xFFFF_F310)
15.1 Register Description
register pairs (ADREG04H/L, ADREG15H/L, ADREG26H/L, ADREG37H/L) and a clock select register
(ADCCLK). The conversion result registers contain the digital values of completed conversions. The clock
select register selects an A/D conversion clock.
The ADC has two mode control registers (ADMOD0 and ADMOD1), four conversion result high/low
