Circuit
type
A
Function
Clock oscillation pins
B
Test input pin
Connect directly to VSS.
C
Reset I/O pin
This pin consists of an N-ch open-drain output with
a pull-up resistor and of hysteresis input. A low
level is output from this pin by internal source. The
internal circuit is initialized by the input of a low
level.
G
General-purpose I/O ports
Also serve as external interrupt input pins. In the
MB89190A series, also serve as analog input pins.
External interrupt input is of hysteresis input type.
D
General-purpose I/O ports
Also serve as external interrupt input.
External interrupt input is of hysteresis input type.
D
General-purpose I/O port
Also serves as clock I/O for the 8-bit serial I/O
interface.
The serial I/O clock input is of hysteresis input type
with a built-in noise filter.
E
General-purpose I/O port
Also serves as a serial I/O data output pin.
D
General-purpose I/O port
Also serves as a serial I/O data input pin.
The serial I/O data input is of hysteresis input type
with a built-in noise filter.
D
General-purpose I/O port
Also serves as an external clock input pin for the 8-
bit timer/counter.
External clock input of the 8-bit timer/counter is
hysteresis input type with a built-in noise filter.
D
General-purpose I/O port
Also serves as the overflow output and external
interrupt input for the 8-bit timer/counter.
External interrupt input is of hysteresis input type
with a built-in noise filter.
