DONE
This bit is valid only when the user-programmable arbitrary waveform is enabled (i.e., the PULS[3:0] bits (b3~0, PULS,...) are set
to ‘1XXX’). This bit determines whether to enable the data writing/reading from RAM.
0: Disable. (default)
1: Enable.
5
RW
This bit is valid only when the user-programmable arbitrary waveform is enabled (i.e., the PULS[3:0] bits (b3~0, PULS,...) are set
to ‘1XXX’). This bit determines read/write direction.
0: Write data to RAM. (default)
1: Read data from RAM.

SAMP[4:0]
These bits are valid only when the user-programmable arbitrary waveform is enabled (i.e., the PULS[3:0] bits (b3~0, PULS,...)
are set to ‘1XXX’). These bits specify the RAM sample address.
00000: The RAM sample address is 0. (default)
00001: The RAM sample address is 1.
00010: The RAM sample address is 2.
......
10001: The RAM sample address is 17.
10010: The RAM sample address is 18.
10011 ~ 11111: The RAM sample address is 19.

WDAT[6:0]
These bits are valid only when the user-programmable arbitrary waveform is enabled (i.e., the PULS[3:0] bits (b3~0, PULS,...)
are set to ‘1XXX’).
These bits contain the template sample data to be stored in RAM which address is specified by the SAMP[4:0] bits (b4~0,
AWG0,...). They are not updated until new template sample data is written.
