The syntax of configuration commands is very simple.
Each 8–bit code word contains a 3–bit parameter code
to specify the parameter and the 3–bit value code to be
selected. Bit 7 of the command code is set to 0 and bit 0
is always a 1. To read the value code of a parameter, one
writes all zeros for the parameter code and puts the
parameter code in place of the parameter value code.
Table 5 shows the details.
The configuration command response byte is similar to
the command byte itself. Bit 0 of the response byte is
always 0. When writing a parameter, the upper 7 bits are
the echo of the command code. When reading a param-
eter, the current value code is returned in bit positions 1
to 3 with the upper 4 bits being the same as sent (see
Table 6).
