Multiplexers
There are four user selectable on-chip multiplexers (A-
MUX, B-MUX, S-MUX and C-MUX).
These four multiplexers support instructions as tabulated
in Table 5.
The MUX instructions are latched such that the instruction
will not start executing until the rising edge of CLK latches the
instruction onto the device.
