Table 72: Transmit Waveform Value For DS1 -15.0 dB LBO
The standard value of the SCAL[5:0] bits is ‘001000’. One step change of the value
results in 12.5% scaling up/down against the pulse amplitude.

Table 73: Transmit Waveform Value For DS1 -22.5 dB LBO
and the pulse amplitude is not set properly, the overlap of two consecu-
tive pulses will make the pulse amplitude overflow (exceed the maxi-
mum limitation). This overflow is captured by the DAC_IS bit, and if
enabled by the DAC_IE bit, an interrupt will be reported by the INT pin.

The standard value of the SCAL[5:0] bits is ‘000100’. One step change of this value
results in 25% scaling up/down against the pulse amplitude.
