I/O Function
Clock XTAL 96 F13 96 96 Input For connection to a
crystal oscillator.
See section 23,
Clock Pulse
Generator, for
typical connection
diagrams for a
crystal resonator
and external clock
input.
EXTAL 97 E13 97 97 Input For connection to a
crystal oscillator.
The EXTAL pin can
also input an
external clock. See
section 23, Clock
Pulse Generator,
for typical
connection
diagrams for a
crystal resonator
and external clock
input.
φ 94 F10 94 94 Output Supplies the system
clock to external
devices.

36 M1 36 36 Output When a synchro-
nous DRAM is
connected, this pin
is connected to the
CLK pin of the
synchronous
DRAM. For details,
refer to section 6,
Bus Controller
(BSC).
