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 HT66FU30, HT66FU40, HT66FU50 and
HT66FU60 devices. All information related to the UART Module will be described in the following UART Mod-
ule section.
