*1: When F

= 50 MHz (frequency), and the machine cycle is 4.0 ns.
The minimum value of the ADCT resister is #A224, differs from that of the MB90F243.
*2: Current when the A/D converter is not operating and the CPU is stopped.
Notes:
The smaller | AVRH – AVRL |, the greater the error would become relatively.
If the output impedance of the external circuit for the analog input is high, sampling period might be
insufficient. When the sampling period set at near the minimum value, the output impedance of the external
circuit should be less than approximately 300
