X1
Connection pins for a crystal or other oscillator circuit.
A
An external clock can be connected to X0. In this case, leave
X1 open.

X1A
Connection pins for a crystal or other oscillator circuit.
A
An external clock can be connected to X0A. In this case, leave
X1A open.
97
94
MOD0
B
Input pin for setting the memory access mode.
Connect directly to VSS.
95, 94 92, 91
P84, P83
J
General-purpose CMOS input port.
96
93
RST
Reset I/O pin. The pin is an N-ch open-drain type with pull-up
C
resistor and hysteresis input. The pin outputs an “L” level when
an internal reset request is present. Inputting an “L” level initial-
izes internal circuits.
