HT46R016/HT46R017

Enhanced A/D 8-Bit OTP MCU

● A/D Inputs

Each device in this series has four inputs to the A/D converter. All of these analog inputs are

pin-shared with I/O pins. If these pins are to be used as A/D inputs and not as I/O pins, then the

corresponding ACEn bits in the A/D converter channel enable control register, ACER, must be

properly setup. If chosen as I/O pins, then full pull-high resistor configurations remain. However,

if used as A/D inputs, then any pull-high resistor configurations associated with these pins will be

automatically disconnected.

I/O Pin Structures

The diagrams illustrate the I/O pin internal structures. As the exact logical construction of the I/O

pin may differ from these drawings, they are supplied as a guide only to assist with the functional

understanding of the I/O pins.
