Function
Pins for connecting the crystal for the main clock. To use an external
clock, input the signal to X0 and leave X1 open.
General-purpose CMOS input port for MB89F202.
General-puspose CMOS I/O port for MB89202/MB89V201.
Reset I/O pin.
This pin serves as an N-channel open-drain reset output with pull-up
resistor (not available for MB89F202) 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.
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 in-
terrupt 2 is a hysteresis input.
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.
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.
General-purpose CMOS I/O ports.
This pin also serves as the data output pin for the UART or 8-bit serial
I/O.
General-purpose CMOS I/O ports.
This pin also serves as the data input pin for the UART or 8-bit serial
I/O. The resource is a hysteresis input.
General-purpose CMOS I/O ports.
This pin also serves as the external clock input pin for the 8/16-bit cap-
ture timer/counter. The resource is a hysteresis input.
General-purpose CMOS I/O ports.
This pin also serves as the output pin for the 8/16-bit capture timer/
counter or as the input pin for external interrupt 1. The resource is a
hysteresis input.
General-purpose CMOS I/O ports.
These pins also serve as the input pin for external interrupt 1. The re-
source is a hysteresis input.
General-purpose CMOS I/O ports.
This pin also serves as the buzzer output pin or the 12-bit PPG output.
General-purpose CMOS I/O ports.
This pin also serves as the 8-bit PWM timer output pin.
