Section 18 A/D Converter
18.7
18.7.1
Operation of the A/D converter can be disabled or enabled using the module stop control register.
The initial setting is for operation of the A/D converter to be halted. Register access is enabled by
clearing the module stop state. When placing the A/D converter in the module stop state after it
performed A/D conversion, be sure to set both of the CKS1 and CKS0 bits to 1 and clear all of the
ADST, TRGS1, TRGS0, and EXTRGS bits to 0 to disable A/D conversion. After that, dummy-
read the ADCSR register and then set the module stop control register. For details on the module
stop control register, see section 24, Power-Down Modes.
18.7.2
When this LSI enters software standby mode with A/D conversion enabled, the analog inputs are
retained, and the analog power supply current is equal to as during A/D conversion. If the analog
power supply current needs to be reduced in software standby mode, set both of the CKS1 and
CKS0 bits to 1 and clear all of the ADST, TRGS1, TRGS0, and EXTRGS bits to 0 to disable A/D
conversion. After that, dummy-read the ADCSR register and then enter software standby mode.
18.7.3
If any of actions (1 to 3 below) is performed while activation by an external trigger* is in use,
stopping A/D conversion may be impossible.
