14.6 Operation in A/D Trigger Mode

Setting the CE bit of the ADSCM0 register to 1 starts A/D conversion immediately.

14.6.1 Operation in select mode

One analog input specified in the ADSCM0 register is A/D converted at a time and the result is stored in
an ADCRm register. Analog inputs correspond one-to-one with ADCRm register (m = 0 to 11).
An A/D conversion termination interrupt (INTAD) is generated for each A/D conversion termination
(CS bit = 0).
To restart A/D conversion, set the CE bit of the ADSCM0 register.
This is optimal for an application that reads a result for each A/D conversion.
Remark: m = 0 to 11
