S1SEL to S4SEL (1 each) : S-1 to S-4 pin status
0 ; S-1 to S-4 pins are not grounded.
1 ; S-1 to S-4 pins are grounded.

S1SEL to S4SEL are actually determined by
comparing the S-1 to S-4 pin DC voltages with
3.5 V.

S-C1 to S-C4 are actually determined by
comparing the S2-1 to S2-4 pin DC voltages
with two threshold. However, when the S-1 to
S-4 pins are open, the outputs are fixed to “3”.

4) Power-on Reset
The CXA2069Q has an internal power-on reset function that sets each control register to “0” during IC
power ON.
The power-on reset VTH has hysteresis.
