amplitude is written as an eight-bit byte, where the

first phase of the symbol is written first.

In serial-port host mode, the amplitude bytes are

written LSB first. The contents of the Arbitrary

Waveform register can be verified by reading the

Waveform Register.

Notes: 1. In Hardware Mode the Diagnostic Modes are selected by directly setting the pins on the device; in Host

Mode, the appropriate register bits are written for Diagnostic Modes.

2. In Host Mode the interrupts can be masked by writing a “1” to the LOS bit; there is no masking in the

Hardware Mode.
