Minimum VDD for F devices is 2.3V.
When the 3x Multiplier mode is selected, the input frequency has to be 16 MHz. When the 4x Multiplier
mode is selected, the input frequency has to be between 8 MHz and 16 MHz.
The dedicated In-Circuit Port is available only on the 44-pin TQFP packaged devices. This bit should be
programmed to a ‘0’ in all other devices. See Section 2.2 “Dedicated ICSP/ICD Port (44-Pin TQFP
Only)” for more information.
