This register allows software to select the length of cable that XPLS is required to
drive and to enable generation of user-programmable output templates.
RPT:
The RPT bit enables the 4-bit DAC codes contained in the Programmable
Template CODE registers to generate the output waveform. When RPT is set
to a logic 1, the internal user-programmable XPLS CODE registers supply the
DAC codes used to generate the waveform. RPT must be set to logic 1 and
the desired template codes programmed for correct output pulse generation.
The Operations section contains the required details for programming the
templates.
SM:
Reserved
The reserved bits must be programmed to logic 0 for correct operation.
