SCAL specifies a scaling factor to be applied to the amplitude of the user-programmable arbitrary pulses which is
to be transmitted if needed. The default value of SCAL[5:0] is ‘100001’. Refer to
trary
= 110110: Default value for T1 0~133 ft, T1 133~266 ft, T1 266~399 ft, T1 399~533 ft, T1 533~655 ft, J1 0~655 ft.
= 100001: Default value for E1 75 Ω and 120 Ω. One step change of this value results in 3% scaling up/down

After ‘1’ is written to this bit, a read or write operation is implemented.
This bit selects read or write operation
= 0: Write to RAM
= 1: Read from RAM
These bits specify the unit interval address. There are totally 4 unit intervals.
= 00: UI address is 0 (The most left UI)
= 01: UI address is 1
= 10: UI address is 2
= 11: UI address is 3
These bits specify the sample address. Each UI has totally 16 samples.
= 0000: Sample address is 0 (The most left sample)
= 0001: Sample address is 1
= 0010: Sample address is 2
……
= 1110: Sample address is 14
= 1111: Sample address is 15
Reserved
In Indirect Write operation, the WDAT[6:0] will be loaded to the pulse template RAM, specifying the amplitude of
the Sample.
After an Indirect Read operation, the amplitude data of the Sample in the pulse template RAM will be output to the
WDAT[6:0].
One step change of this value results in 2% scaling up/down against the pulse amplitude.
against the pulse amplitude.
