The A/D conversion result is loaded from the successive approximation register to this register each time A/D
conversion is completed, and the ADCRH register stores the higher 8 bits of the A/D conversion result.
Caution When data is read from ADCR and ADCRH, a wait cycle is generated. Do not read data from
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. When using at least one port of port 2 as
a digital port or for segment output, set it to the same potential as the V
The signal input to ANI0 to ANI5 is converted into a digital signal, based on the voltage applied across AV
AV
This is the ground potential pin of the A/D converter. Always use this pin at the same potential as that of the V
pin even when the A/D converter is not used.
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 ANI5/P25 pins to analog input of 10-bit successive approximation type 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 ANI5/P25 pins to input or output.
This register switches the ANI0/P20 to ANI5/P25 pins to I/O of port, analog input of A/D converter, or segment
output.
