• Manufacturer: Renesas Electronics Corporation.

11.4.3 Operation mode
Four operation modes are described below. The operation modes are set with bits MS and PLM of the
ADSCM0H register (refer to 11.3 ”Control Registers” on page 371).
(1)
Select mode
In this mode, a single A/D conversion of one analog input specified with bits ANIS3 - ANIS00 of
the ADSCM0L register is performed.
The conversion result for that analog input is saved to the ADA0CRn register. A/D conversion
starts upon detection of a trigger, and the A/D conversion interrupt (INTAD) is output upon each
conversion completion.
