Pins for connecting the crystal for the main clock. To use an
external clock, input the signal to X0 and leave X1 open.

RST
C
Reset I/O pin.
This pin serves as an N-ch open-drain reset output and a reset input
as well. The reset is a hysteresis input.
It outputs the "L" signal in response to an internal reset request.
Also, it initializes the internal circuit upon input of the "L" signal.

G
General-purpose CMOS I/O ports.
These pins also serve as an input (wake-up input) of external
interrupt 2 or as an 10-bit A/D converter analog input. The input of
external interrupt 2 is a hysteresis input.
