Clock OSC1 11 11 Input
OSC2/CLKOUT 10 10 Output
Pins to be connected to a
crystal or ceramic
resonator for the system
clock. An external clock
can also be input to
OSC1. When the on-chip
oscillator is not used, the
system clock signal can
be output from OSC2. For
connection examples, see
section 5, Clock Pulse
Generator.
