Function code

The eight-bit function code (FC0 to FC7) is determined

by the number of the key pressed and the SEL and FCS1

to FCS3 inputs.

When SEL is LOW, bits FC3 and FC7 of the function

codes for the 64 keys are determined by FCS1 and FCS3,

respectively, as shown in tabel 4 and the following figure.

Note

× = don’t care

− = key press code

The function codes when SEL is LOW, FCS1 is HIGH

and FCS3 is LOW are shown in the following figure. For

example, when key 23 is pressed, the generated function

code is 2EH.

When SEL is HIGH, the function codes for keys 1 to 32

are fixed, and bits FC3, FC6 and FC7 of the function

codes for keys 33 to 64 are determined by FCS1 to FCS3

as shown in table 5 and the following figure.
