• Description
When determining key on/off and reading key data, the controller must confirm the state of DO output when CE is
low. When DO is low, the controller recognizes that a key has been pressed and reads the key data. After the time
t8, the next key on/off determination and reading key data must be confirmed by the state of DO output when CE is
low. During this operation t8 must obey the following condition:
t8 > t4
If key data is read when DO is high, the key data (KD1 to KD30) and the sleep acknowledge data (SA) will be
invalid.
