Functional Description
IDT82P2284
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.

the pulse amplitude is not set properly, the overlap of two consecutive
pulses will make the pulse amplitude overflow (exceed the maximum
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.
