CT will send at least three words if we press a
legal key. CT may send three or four words, or
several words depending on the length of time
the legal key is pressed. (see Fig. 12)
Power on reset function (PRB)
The power on reset function can be activated by
connecting a capacitor to PRB pin while power
is applied. The time (t
C
) must be longer than
0.1ms when the voltage in PRB pin (V
C
) be-
comes higher than 0.3V
DD
after the voltage in
V
DD
pin exceeds 2.2V.
When the power on reset function is activated,
the standby state continues until an L is in-
put to IE0~IE3.
