S-OUT Pin
By going low whenever the carrier frequency is output from the REM pin, the S-OUT pin indicates that
communication is in progress.
The S-OUT pin is CMOS output.
The S-OUT pin goes high on reset.

S-IN Pin (D
0
bit of P
1
)
To input serial data, use the S-IN pin. When control register (P
1
) is set to serial input mode, the S-IN pin is
connected as an input to the LSB of the accumulator; the S-IN pin is pulled down to the V
SS
level within the LSI.
In this state, if the rotate-left accumulator instruction (RL A) is executed, the data on the S-IN pin is copied to the
LSB of the accumulator.
If the control register is released from serial input mode, the S-IN pin goes into a high-impedance state, but no
through current flows internally. When the RL A instruction is executed, the MSB is copied to the LSB.
At reset (all cleared), the S-IN pin goes into a high-impedance state.
