The A/D converter converts analog input signals into digital values, has a resolution of 10 bits, and can handle 8 analog
The A/D converter has the following features.
(1) 10-bit resolution A/D conversion
(2) Power-fail detection function
10-bit resolution
8 channels
Successive approximation method
Operating voltage: AV
Analog input voltage: 0 V to AV
The following functions are provided as operation modes.
• Continuous select mode
• Continuous scan mode
• One-shot select mode
• One-shot scan mode
The following functions are provided as trigger modes.
• Software trigger mode
• External trigger mode (external, 1)
• Timer trigger mode
Power-fail monitor function (conversion result compare function)
An analog input channel is selected from ANI0 to ANI7, and an A/D conversion operation is repeated at a resolution
of 10 bits. Each time A/D conversion has been completed, an interrupt request signal (INTAD) is generated.
This function is used to detect a drop in the battery voltage. The result of A/D conversion (the value of the
ADA0CRnH register) is compared with the value of the ADA0PFT register, and the INTAD signal is generated only
when a specified comparison condition is satisfied (n = 0 to 7).
