CONTROL DATA
S0, S1: SLEEP CONTROL DATA
These control data bits switch between normal mode and sleep mode and set the states of the KS1 to
KS6 key scan outputs during key scan standby.
Note: This assumes that the KS1/S54 and KS2/S55 output pins are selected for key scan output.
K0, K1: KEY SCAN OUTPUT/SEGMENT OUTPUT SELECTION DATA
These control data bits switch the functions of the KS1/S54 and KS2/S55 output pins between key
scan output and segment output.
Notes:
1. X=Don’t care
2. KSn (n=1 or 2): Key scan output
3. Sn (n=54 or 55): Segment output
