Note: If a key data read operation is executed when DO is high, the read key data (KD1 to KD30) and sleep
acknowledge data(SA) 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 output pins and the KI1 to KI5 input pins and
one of those keys 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 states of the KS1 to KS6 output pins during key scan standby are set to low for KS1 and KS2 and to high
for KS3 to KS6 by the KC1 to KC6 bits in the control data and a key matrix of up to 20 keys is formed from the KS3
to KS6 output pins and the KI1 to KI5 input pins, the KD1 to KD10 key data bits will be set to 0.
2. SA: Sleep acknowledge data
This output data bit is set to the state when the key was pressed. Also, while DO will be low in this case, if serial data
is input and the mode is set (to normal or sleep mode) during this period, that mode will be set. SA will be 1 in sleep
mode and 0 in normal mode.
