Description
External Crystal Input. This is the input pin to the crystal oscillator. A crystal
can be connected between it and the
signal is usable with external RC networks and an external clock driver.
External Crystal Output. This pin is the output of the crystal oscillator. A
crystal can be connected between it and the XIN pin to form the oscillator.
When the system clock is referred to in this manual, it refers to the frequency
of the signal at this pin. This pin must be left unconnected when not using a
crystal.
RC Oscillator Output. This signal is the output of the RC oscillator. It is
multiplexed with a general-purpose I/O pin. This signal must be left
unconnected when not using a crystal.
Debug. This pin is the control and data input and output to and from the On-
Chip Debugger. This pin is open-drain.
For operation of the On-Chip Debugger, all power pins (V
