Pin Circuit
name type
A Pins for connecting the crystal for the main clock. To use an
external clock, input the signal to X0 and leave X1 open.
H / E General-purpose CMOS input port.
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.
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.
D General-purpose CMOS I/O ports.
These pins also serve as an input (wake-up input) of external
interrupt 2. The input of external interrupt 2 is a hysteresis input.
B General-purpose CMOS I/O ports.
This pin also serves as the clock I/O pin for the UART or 8-bit
serial I/O. The resource is a hysteresis input.
E General-purpose CMOS I/O ports.
This pin also serves as the data output pin for the UART or 8-bit
serial I/O.
