21 / 187 page  Rev. 1.10 �1 of 187 ���� �1� �01� A/D Flash 8051 Core Low Pin Count MCU HT85F2250/HT85F2262 6 Pin Descriptions With the exception of the power pins, all pins on these devices can be referenced by their Port name, e.g. P0.0, P0.1 etc, which refer to the digital I/O function of the pins. However these Port pins are also shared with other function such as the Analog to Digital Converter, Serial Port pins etc. The function of each pin is listed in the following table, however the details behind how each pin is configured is contained in other sections of the datasheet.
