Technical Data

These signals are used to support the on-chip clock generation circuitry.
This input signal is always driven by an external clock input except when
used as a connection to the external crystal when the internal oscillator
circuit is used. The clock source is configured during reset.
This output signal is used as a connection to the external crystal when
the internal oscillator circuit is used. XTAL should be grounded when
using an external clock input.
This output signal reflects the internal system clock.
These are dedicated quiet power and ground supply signals for the
frequency synthesizer circuit.
In addition to the function stated here, these signals can be configured
as discrete I/O signals also.
These three-state bidirectional signals provide the general-purpose data
path between the microcontroller unit (MCU) and all other devices.
