Output Data

• 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 KS1/P1 and KS2/P2 output pins are set to function as general-purpose output ports with the "set key scan

output port/general-purpose output port state" instruction 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.

• 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.
