2. When CL is stopped at the high level
Note: If a key data read operation is executed when DO is high, the read key data (KD1 to KD30) will be invalid.
Output Data
1.KD1 to KD30: Key data
When a key matrix of up to 30 keys is formed from the KS1 to KS6 key scan output pins and the KI1 to KI5 key scan
input pins and one of those key is pressed, the key output data corresponding to that key will be set to 1. The table
shows the relationship between those pins and the key data bits.
When the KS4/P4 to KS6/P2 output pins are set to function as the general-purpose output ports with the control data
“KP1 and KP2”, and a key matrix of up to 15 keys is formed from the KS1 to KS3 output pins and the KI1 to KI5 input
pins, the KD16 to KD30 key data bits will be set to 0.
