Note:

As devices exist in more than one package format, the table reflects the situation for the package with the most

pins.

There is an additional peripheral known as the UART module in HT68FU30, HT68FU40, HT68FU50 and

HT68FU60 devices. All information related to the UART Module will be described in the following UART Mod-

ule section.
