Crystal or other resonator connector pins for the main
clock
A
The external clock can be connected to X0. When this
is done, be sure to leave X1 open.
CR oscillation selectability in model with a mask ROM
only.
A hysteresis input type
C
Memory access mode setting pins
Connect directly to VSS.

RST
Reset I/O pin
This pin is an N-ch open-drain output type with a pull-
D
up resistor, and a hysteresis input type. “L” is output
from this pin by an internal reset request (optional).
The internal circuit is initialized by the input of “L”.
