1.5.7 PC0-PC3
These four I/O lines comprise port C. The state of any pin is software
programmable and all port C lines are configured as input during
power-on or reset. See 4.6 Input/Output Programmingf.
1.5.8 XFC
This pin provides a means for connecting an external filter capacitor to
the synthesizer phase-locked loop filter. See 6.4 Phase-Locked Loop
Synthesizer for additional information concerning this capacitor.
1.5.9 VDDSYN
This pin provides a separate power connection to the PLL synthesizer
which should be at the same potential as VDD.
NOTE:
Any unused inputs and I/O ports should be tied to an appropriate logic
level (either VDD or VSS). Although the I/O ports of the MC68HC05E1 do
not require termination, it is recommended to reduce the possibility of
static damage.
