QUALIFY/SQRAM DATA REGISTER <5>
The qualify/SQRAM data register consists of A03U106 and A03U108.
This register is shared by two separate functions. When loading parameters into the SQRAM, A03U106 and A03U108 are
used as the data register. To provide data to the SQRAM, the MPU writes the data into A03U106 and A03U108 at I/O
addresses 50
hex
and 51
hex
, respectively. The data format is illustrated in Figure 4-4. The outputs of A03U106 and A03U108 are connected
to the SQRAM inputs. The signal, LDSQRAM (A03U108 pin 14), is high when data is loaded from this data register into
the SQRAM.
During an acquisition, A03U106 and A03U108 are used as the qualify register. Qualify data and other control bits are
written to them at I/O addresses 50
hex
and 51
hex
respectively. The format is illustrated in Figure 4-5.
