This circuit controls the conversion time of an input analog signal that is to be converted into a digital signal, as
well as starting and stopping of the conversion operation. When A/D conversion has been completed, this
controller generates INTAD.
This pin inputs an analog power/reference voltage to the A/D converter. The signal input to ANI0 to ANI15 is
converted into a digital signal, based on the voltage applied across AV
supplied to AV
P157/ANI15 are used as digital I/Os or analog inputs.
This is the ground potential pin of the A/D converter. Always use this pin at the same potential as that of the
EV
This register is used to set the conversion time of the analog input signal to be converted, and to start or stop the
conversion operation.
This register switches the ANI0/P20 to ANI7/P27 and ANI8/P150 to ANI15/P157 pins to analog input of A/D
converter or digital I/O of port.
This register is used to specify the port that inputs the analog voltage to be converted into a digital signal.
This register switches the ANI0/P20 to ANI7/P27 and ANI8/P150 to ANI15/P157 pins to input or output.
Note AV
Using at least one pin as an analog input and using all
pins not as digital I/Os
Pins used as analog inputs and digital I/Os are
mixed
Using at least one pin as a digital I/O and using all pins
not as analog inputs
