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 ANI7 is
converted into a digital signal, based on the voltage applied across AV
supplied to AV
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
and V
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 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 pins to input or output.
