5.7.1
A/D converter functions
The A/D converter converts input analog voltages to digital signals with an 8-bit or 10-bit resolution. It can control
up to eight analog input channels (ANI0 to ANI7).
A/D conversion can be started only by software.
One of analog inputs ANI0 to ANI7 is selected for A/D conversion. A/D conversion is performed repeatedly, with
an interrupt request (INTAD0) being issued each time an A/D conversion is completed.
Caution
In standby mode, the A/D converter operation is disabled.
5.7.2
A/D converter configuration
The A/D converter consists of the following hardware.
