Analog-to-Digital Converter (ADC12B8CV2)
This buffer can be turned on or off with the ATDDIEN register for each ATD input pin.
This is important so that the buffer does not draw excess current when an ATD input pin is selected as
analog input to the ADC12B8C.
12.5 Resets
At reset the ADC12B8C is in a power down state. The reset state of each individual bit is listed within the
Register Description section (see Section 12.3.2, “Register Descriptions”) which details the registers and
their bit-field.
12.6 Interrupts
The interrupts requested by the ADC12B8C are listed in Table 12-24. Refer to MCU specification for
related vector address and priority.
