Electrical Characteristics
The system clock input XTAL is used to generate the main system clock. It supplies the PLLs and other
peripherals. The system clock input can be connected to either external oscillator or a crystal using internal
oscillator amplifier.
CKIH1 and CKIH2 provide additional clock source option for peripherals that require specific and
accurate frequencies.
