Each slot outputs noise using the output of the LFO noise oscillator. At this time, the LFO parameters ("LFORE", "LFOF", "ALFOWS", "ALFOS",
"PLFOWS" and "PLFOS" have no effect on noise as audio data.
Also, as shown in Figure 4.9, when LFO is used for low frequency modulation and the LFO waveform selection is set to noise (ALFOWS = "3H" or PLFOWS = "3H"), reset by "LFORE" is not applied. Hmm. The frequency cannot be changed. This means that when selecting noise, the LFO can select the waveform, but it cannot change the other parameters.

SA [19: 0] (R / W); Start Address
When sounding using waveform data in memory, specify the start address of the waveform data with a byte address. However, if the waveform data is in “16-bit PCM format” (“PCM8B” = “0B”), be sure to set the value of the least significant bit (SA0) of the register to “0B”.

LSA [15: 0] (R / W); Loop Start Address
The sound data loop start address is expressed as the number of samples from "SA".

LEA [15: 0] (R / W); Loop End Address
Indicates the loop end address of the sound data as the number of samples from “SA”.

PCM8B (R / W); PCM 8Bit
Specify the word length (format) of waveform data.
