Note: 1. If the pin-shared pin functions have multiple outputs simultaneously, its pin names at the right side of the
"/" sign can be used for higher priority.
2. The OCDSDA and OCDSCK pins are the OCDS dedicated pins and only available for the
BS82BV12A-3, BS82CV16A-3 and BS82DV20A-3 devices, which are the OCDS EV chips for the
BS82B12A-3, BS82C16A-3 and BS82D20A-3 devices respectively.
Pin Descriptions
With the exception of the power pins and some relevant transformer control pins, all pins on the
device can be referenced by their Port name, e.g. PA0, PA1, 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 Touch
Key function, Timer Modules, etc. The function of each pin is listed in the following tables, however
the details behind how each pin is configured is contained in other sections of the datasheet.
As the Pin Description table shows the situation for the package with the most pins, not all pins in
the table will be available on smaller package sizes.
