Section 22 A/D Converter
22.7
22.7.1
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. Set the CKS1 and CKS2 bits to 1 and clear the ADST, TRGS1,
TRGS0, and EXTRGS bits all to 0 to disable A/D conversion when entering module stop state
after operation of the A/D converter. After that, set the module stop control register after executing
a dummy read by one word. For details, see section 28, Power-Down Modes.
22.7.2
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 the CKS1 and CKS2 bits
to 1 and clear the ADST, TRGS1, TRGS0, and EXTRGS bits all to 0 to disable A/D conversion.
After that, enter software standby mode after executing a dummy read by one word.
22.7.3
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.
