The last table of 160 words contains sync symmetry values as a function of frequency when sines or squares
are selected. There are three values which precede the table: these are used to control the sync duty cycle
for triangles, ramps, and noise.
392 TRI_SYM Triangle sync symmetry.0 to 4095. Nominal 2048.
393 RAMP_SYM Ramp sync symmetry. 0 to 4095. Nominal 2048.
394 NOISE_SYM Noise sync duty. 0 to 4095. Nominal 2048
395 SYM_0 0 to 4095. Nominal 2048. For dc to 19530 Hz.
396 SYM_1 0 to 4095. Nominal 2048. For 19,531 to 39,062 Hz.
397 SYM_2 0 to 4095. Nominal 2048. For 39,063 to 58,593 Hz.
