(1) Trigger mode
There are three types of trigger modes which serve as the start timing of A/D conversion processing: A/D trigger
mode, timer trigger mode, and external trigger mode. These trigger modes are set by the ADM0 register.
(a) A/D trigger mode
Generates the conversion timing of the analog input for the ANI0 to ANI15 pins inside the A/D converter
unit.
(b) Timer trigger mode
Specifies the conversion timing of the analog input set for the ANI0 to ANI15 pins using the values set
to the RPU compare register.
This register creates the analog input conversion timing by generating the coincidence interrupts of the
capture/compare registers (CC03) connected to the 24-bit TM10.
(c) External trigger mode
Mode which specifies the conversion timing of the analog input to the ANI0 to ANI15 pins using the ADTRG
pin.
(2) Operation mode
There are two types of operation modes which set the ANI0 to ANI15 pins: select mode and scan mode. The
select mode has sub-modes including the one-buffer mode and four-buffer mode. These modes are set by
the ADM0 register.
