The A/D conversion result is loaded from the successive approximation register to this register each time A/D
conversion is completed, and the ADCR register holds the A/D conversion result in its lower 10 bits (the higher 6
bits are fixed to 0).
The A/D conversion result is loaded from the successive approximation register to this register each time A/D
conversion is completed, and the ADCRL register stores the lower 8 bits of the A/D conversion result.
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, ADCRL, and ADCRH, a wait cycle is generated. Do not read data
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 all the specified A/D conversion has been
completed, this controller generates an A/D conversion end interrupt request signal (INTAD).
This pin inputs an analog power/reference voltage to the A/D converter. Make this pin the same potential as the
V
The signal input to ANI0 to ANI10 is converted into a digital signal, based on the voltage applied across AV
and 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 is the ground potential pin. In the 78K0/KY2-L and 78K0/KA2-L, V
