Features
Atmel ATmega16/32/64/M1/C1
•
•
The ATmega16/32/64/M1/C1 features a 100µA ±5% Current Source. After RESET or up on
request, the current is flowing through an external resistor. The voltage can be measured on
the dedicated pin shared with the ADC. Using a resistor in serie with a
ommended. To protect the device against big values, the ADC must be configured with AVcc
as internal reference to perform the first measurement. Afterwards, another internal reference
can be chosen according to the previous measured value to refine the result.
When ISRCEN bit is set, the ISRC pin sources 100µA. Otherwise this pin keeps its initial
function.
