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.
11.6
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 can be pulled down to the V
SS
level by a mask option from 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.
Caution
The
μ
PD6123 is not provided with an S-IN pin.
