0 None (disabled).
1
Square wave.

If set, the function generator frequency is in units of 0.01 Hz. If clear, the frequency is in units
of Hz.
9-11
Reserved.
12
One-shot mode if set. If bit 12 is set and bit 13 is clear, the function code is reset to zero
(disabled) after one complete waveform. If bits 12 and 13 are both set, the function code is
reset to zero after two waveforms.
13
Invert every other period if set.
14-15 Reserved for future use.
The function code programmed into bits 0-1 defines the type of waveform to be generated:
Code Description
0
None (disabled).
1
Square wave.
2
Sine wave.
Note that the drive is placed under control of the function generator by setting
Desired State (0x24) to one of the following values:
4 (function generator drives current loop);
14 (function generator drives velocity loop);
24 (function generator drives position loop in servo mode);
34 (function generator drives position loop in stepper mode).
Note that if one-shot mode is selected, then after one period (two if invert is selected)
the function type will reset to zero.
