A single D output line is set to logic 1, if data of Y-register is
between 0 to 7.
Carrier frequency come out from REMOUT port, if data of
Y-register is 8.
All D output line is set to logic 1, if data of Y-register is 9.
It is no operation, if data of Y-register between 10 to 15.
When Y is between Ah and Dh, one of R output lines is set at
logic 1.
When Y is Eh, the output of R is set at logic 1.
When Y is Fh, the output D0~D9 and R are set at logic 1.
Data of Y-register is between 0 to 7, selects appropriate D
output.
Data of Y-register is 8, selects REMOUT port.
Data of Y-register is 9, selects all D port.
Data in Y-register, when between Ah and Dh, selects an
appropriate R output (R0~R3).
Data in Y-register, when it is Eh, selects all of R0~R3.
Data in Y-register, when it is Fh, selects all of D0~D9 and
R0~R3.
