3.3.8 Writing a Parameter
To read or write parameters, change the SEL2, SEL1 and SEL0 bits to those specified in the table below.
Reading or writing is made at the activating edge of the read command or write command bit.
Designate the parameter number in low order bits of word +14.

・
The SEL signals are data selection signals as shown in the table above.
The data is determined according to the combination among SEL0 (%QX*14.2), SEL1 (%QX*14.3)
and SEL2 (%QX*14.4).
・
When the reading completion bit is turned on, the parameter is established.
・ When the overwrite completion bit is turned on, you can change word 12.
・
If the overwrite fails, the data error bit is turned on.
When SEL2, SEL1 and SEL0 are updated, CSEL2, CSEL1 and CSEL0 change to the same pattern
and you can notice modification of the IQ area.
