Note: 1. If the pin-shared pin f�nctions have m��tip�e o�tp�ts sim��taneo�s�� its pin names at the right side of

the “/” sign can be �sed for higher priorit�.

�. Both rea� IC and OCDS EV IC share the same package.

�. The TDA and TCK pins are the OCDS de�icated pins and on�� avai�ab�e for the HT8�V��40 device

which is the OCDS EV chip for both the HT8�F��40 and HT8�F��0 devices.
