Fig. 30 External clock input waveform
Key-on wakeup
When system returns from RAM back-up state by using the
G
0
/INT pin, select the return edge (rising edge or falling edge)
with the bit 2 of register K0 according to the external state
before going into the RAM back-up state.
When system returns from RAM back-up state by using the
ports G
1
–G
3
and S
0
–S

, set the port using the key-on wakeup
function selected with register K0 to “H” level before going into
the RAM back-up state.

share the circuit which is
used to detect the edge and to recognize “L” level.
The G
0
/INT pin cannot be set to “no key-on wakeup.”
External clock input waveform
When the external clock is used, open X
OUT
pin, and input the
clock waveform into X
IN
pin shown below. (Refer to Figure 30)
Duty ratio = 50 %.
“
H
” level input voltage=

(V).
CR oscillation constant
Use the external 30 pF capacitor and enable to change the
frequency by the external resistor.
Test the system sufficiently because the oscillation constant
depends on the ROM type (mask ROM or PROM).
