I/O
P4.1: User-configurable I/O Port 4 bit 1.
XTAL2: Output from inverting oscillator amplifier. It may be used as a port pin if the
internal RC oscillator is selected as the clock source.
CLKOUT: When the internal RC oscillator is selected as the clock source, may be
used to output the internal clock divided by 2.
DDA: Serial Data input/output for On-chip Debug Interface when OCD is enabled
and the external clock is selected as the clock source.
